Confused Demo
from Simon Jackson
While the demo is playing, hold A + B + C. Sonic will get confused, lose his place, and possibly die.

Control Mode
At the title screen, press Up, C, Down, C, Left, C, Right. While playing, you can pause the game and use A to restart, B for slow motion, and C for frame
advance.

Debug Mode
Enable Control Mode. After pressing Start to begin a game, hold A until you see Sonic. If you see a bunch of hex numbers on the top of the screen, you're in
Debug Mode.

To start debugging, press B, then you can select any sprite in that level and put it on the screen. To select a different sprite, press A, and to place it on the
screen, press C. Note that sprite selection is different from Zone to Zone. Also, instead of displaying the time elapsed, it displays the number of sprites
currently on the screen. Control Mode functions work as well.

Note: This only works on the first production releases of Sonic.

Extra Lives
In Green Hill Zone - Act 3, there is a 1-Up at the very bottom of the level. Collect it along with enough rings to make 100 for a second life. Next, grab the
1-Up at the top of the loop-de-loop and die. Repeat until you have enough lives.

Get all Emeralds
This cheat allows you to start at the First Level with all the Emeralds, and with lots of Continues. Use the Level Select cheat (see above) to get to the Special
Zone. When you get the Emerald, and have entered into the First Zone, press Reset.

Use the Level Select cheat to get to the Special Zone again. When you get the next Emerald, and have entered the First Zone, press Reset again.

When you have all the Emeralds, continue on with the first level. You get to keep the Emeralds and the Continues accumulated so far.

Level Select
At the title screen, hold A then press Up, Down, Left, Right. When you hear the chime, press Start.

If that doesn't work, try this: at the title screen, press Up, Down, Left, Right, hold A, and press Start. After doing this once, you only need to hold Start +
A to enter the level select.

Marble Zone Shortcut
from Ken and Renee Clay (kclay@bellsouth.net)

jump through the wall on the right again, but be careful of the other chandelier.

Scrap Brain Teleport
On the last level (Scrap Brain), find the ledges that move right then left. Go to the left side of the wall and wait for the platform to move. As soon as it starts to
move left, duck. You'll go through the wall. While here, press Left to teleport right and Right to teleport to the left.

the floor. Break open the tube and go through it. When you come out you will see a Ring Box next to a tower. Climb up the tower and on the top you will find
one 1-up. Glide left and you will find another 1-up. Glide to the left one more time and you will find yet one more 1-up. Since you won't want to go through
the level again just glide to the right until you get to the tower you started from. Get on that first tower and glide to the right. The Act will be over and you will

sounds in this order: 4, 1, 2, 6. You should hear the music you get when you win a chaos emerald. Now select any level, get 50 rings, and jump.

Super Tails
While in Debug Mode, create and position a "Transfer Box" monitor. When you hit it and you are Super Sonic, you lose all your powers but stay yellow. Tails
looks the same but has invincibility (little stars flashing around him.)

To regain Super Sonic, let yourself get hit, then turn into a ring (press B) and place at least 50 rings on Tails. Exit debug mode (press B) and jump to become
Super Sonic with Super Tails as a follower.

from Bo Bayles and sybrgoku@rocketmail.com

hit them. As soon as you are invincible, walk through them. Jump on the platforms to the right and half the level will be finished.

Codes - Sonic 3 - Genesis

Different Battle Music
from Tony (rzor1@aol.com)
Just before Before you fight Robotnik in the Hydrocity Zone, act 2, the boss music will come. Keep Sonic's head under the shallow water until he is about to
drown, then pop out of the water. You will hear the boss music from Sonic and Knuckles.

and repeat the process until you have them all.

Alternatively, enter the Sound Test code and play sounds 2, 4, 5, 6 in order. If you did it correctly, the Emerald sound will play.

To do this trick you must get to the first level of the Launch Base Zone. Set off the first alarm, stop Sonic in the middle of it, and do a Spin-Dash attack. The
flybots will continue to attack, and eventually their value will increase to 10,000 points! Every five flybots will gain you a life and, if you're patient enough, you

Repeat this process and you can gain up to 900 rings and several 1-ups.

Level Select
from DeepC3603@aol.com
There are two level select codes for Sonic 3. The second method is easier, but requires a copy of Sonic 2. Here's how to do each of them:

Method 1:
Immediately after the SEGA screen appears, Sonic will charge at you in a ball. While he's doing this, quickly press Up, Up, Down, Down, Up, Up, Up,
Up. Timing on this trick is crucial.

Method 2:
This code requires a Sonic 2 cartridge. Insert Sonic 2 and enter the Sonic 2 Level Select (play sounds 19, 65, 09, and 17). Return to the title screen,
hold A and press Start. To transfer this to Sonic 3, hold A and carefully remove the cartridge without turning off the Genesis. Insert Sonic 3 and press
Reset. Finally, release A and press Down twice at the main menu.

Note: You'll notice a few levels you haven't seen before, but you can't select them. Since the U.S. version is only 16 megs compared to the Japanese 24-meg
cart, those levels had to go.

Oil Ocean Music
from Roadkill! (roadkill6@hotmail.com)
Here's a way to play the Oil Ocean music through the whole game. Go to the OPTIONS screen and enter sounds 1, 9, 9, 2, 1, 1, 2, 4. You should hear the
Oil Ocean music. Next, hold A + Start and you should return to the SEGA screen with the Oil Ocean music still playing.

Play at Night
from Pingi Maida Guadalupe (elyu98a@prodigy.com)
Enter the Level Select code, then press C + Start to choose your starting level.

Random Starting Location
Enter the Level Select code and choose a level. Pause the game and press A to return to the Level Select menu. Select another level and you will start in a
different area. Beware, for you may start out in a wall.

Secret Special Stage
from Sub Zero (sub.zero@mailexcite.com)
For a bonus stage, enable Level Select, then play tune 1F. Finally, highlight stage 2 and hold A while pressing Start.

Slow Motion
First enable Level Select. While playing, you can pause the game and press A to restart, B for slow motion, and C for frame advance.

Sound Test
from Tim Barr (tsbarr@hotmail.com)

Super Shortcut in Competition
from bbayles@geocities.com
Go to Competition and select Balloon Park. Instead of going forward, fall down backward to land on a yellow balloon. Hold LEFT, You should walk on the
ceiling. You will disappear and keep going until you win!

Super Sonic
To become Super Sonic without getting all the Chaos Emeralds, first enable the level select and debug mode. When the game begins, create a power-up box.
There should be an 'S' on the box. Jump on it to grab 50 rings and become Super Sonic!

Super Tails
from Greg Rozelle (greg@hotmail.com)
Enable Level Select, then press Down to make sure you have the sound test (don't select it yet). Start a one-player game and choose Tails in the Data Select
screen. When the timer appears, press RESET.

Enter the Sound Test menu and choose any zone. Hold A and press Start. You should be Tails and be in debug mode. From here press B, then press A until
you see a box. Press C to select it, then press B to return to Tails.

To enable Super Tails, jump on the box. Tails will look weird and can not be hurt or lose any rings. He can still get squashed and drowned, though, so be
careful in the Ice Cap zone. You will have do this at the beginning of each zone. Robotnik can hurt him at the very end of Launch Base zone-act 2.

View Animations
Enter Debug Mode and press B + C. You'll be treated to a view of Sonic and Tail's moves

Codes - Sonic & Knuckles - PC

Bonus Rounds
from Anthony LaVorgna Jr.
To play the bonus rounds at any time, insert any game into your Sonic & Knuckles cartridge. When the "No Way" message appears, hold A + B + C and
press Start. If you do this with the original Sonic game you can play the levels in order and will be given a password to save your progress.

Note: In case you're wondering, I've left out the passwords deliberately. There are over 32,000 bonus rounds in Sonic & Knuckles. I can't possibly list them
all on the page, nor is there much point to doing so since the levels are nearly identical. Thank you.

Debug Mode when Linked to Sonic 3
from Kyle Wightman
There are two normal ways to get debug mode without a GameShark:

Method 1: Activate level select and hold A and press Start while selecting any stage.

Method 2: Follow the intructions for the easier method in Sonic 3.

Codes - Sonic Adventure - Dreamcast

Play as Super Sonic
Play through the game with every character and the 7th character "Super Sonic" will be opened. This is the only real way to fight Perfect Chaos, the final boss. Submitted by The Notorious C.A.B (Mesosymon@aol.com)

Sonic Tokens
You can get 5 Sonic Tokens from Chao Race. Just raise a chao then go to the Chao Race chose the first choice and then the place where your chao is. Then chose a crystal and win each one then a 5th one will appear and chose it. If you have trouble finding levels you have beat and want the tokens go to the main options at the chose the second option. You can go to any level you have beaten with out running around for it. This is good if you need to collect more tokens and it tells you which ones you have gotten and where. There are Tokens hidden around the world which shouldn't be to hard to find. I have 114 tokens and missing 6 with Sonic. Submitted by Jimmy Haver

Super Speed with Sonic
If you have trouble beating time trial with Sonic constantly click X or B and you will spin real fast. In some levels you have to do this to beat time trial. Submitted by Jimmy Haver (Chocobo4@juno.com)

[ The following codes were submitted by JagarXK180@aol.com but I believe he/she got them from the Ultimate Sonic Adventure FAQ found here. ]

A Clone of Knuckles
Play through the game (with all the characters) until you get Super Sonic. In Super Sonics Adventure, go to the crashed island. There you see Knuckles and Eggman (Robotnik). After the clip, press A+B+X+Y+Start. Then choose Knuckles. Go to the same place, and there are two Knuckles! This works with other characters, too, but it's not as funny.

Aztec Forest Shortcut
To get to the Frog and the Emerald as Tails in one step do as fallows. After riding the trolly to the Aztec Forest you should be standing up high on a platform overlooking the forest. If you stand on the edge and look down and to the left you will see two trees sticking out of the canopy that are close together. Fly toward the trees and land next to the one that is closest to the ledge you jumped from. You should be standing on top of the canopy. Walk around the first tree until you fall through the canopy and end up right by the emerald and the frog.

Better Chao Parenting
Instead of throwing a Chao against a wall to hatch it, try just rubbing the egg like you were rubbing the Chao. Then set it down and back away. It will start jumping, and then it will hatch. They seem to like you better if you do this.

Black Morphing Chao
First you have to be the robot. To get a black chao go into the egg catcher and go to the bridge. On the bridge you see three doors. Go in the one with the prison. Open the middle cell by jumping on the peg and take the egg back to the bridge. On the bridge go behind the chair Robotnik sits on, behind it is a door with 6 buttons in front of it, stomp on them in an order that spells E-G-G-M-A-N and the door will open. while still holding the egg step into the teleporter in the room, then you'll be in the egg catcher chao garden, now just hatch the egg

Change View in Twinkle Park Race
To change the view in Twinkle Park Race, press UP to toggle between inside, outside, and far out view. This also works when playing the first bumper car portion of the level.

Clean Pause
To remove the pause menu, press X and Y together at the pause menu. This is good if you want to take screenshots.

Drive with anyone in Twinkle Circuit.
After completing the game with all six characters, you will be able to race in Twinkle Circuit with anyone. Just select the character you want, then go to station square. Once your there, go over to the little patch of grass and weeds by speed highway entrance, and pick up the ticket. (It will be rotating, and easy to spot.) Then go into the Twinkle Park building, and instead of entering Twinkle Park, enter Twinkle Circuit. You will hear a special noise that tells you that the secret is unlocked. Now just repeat the process for all the characters. Best racers: Knuckles Sonic Tails E-102 Big Amy

Easy Emblems as Knuckles
If you are having trouble getting the 1 minute emlems as Knuckles, here is a trick that will make it much easier. Find the first emerald shard, but don't touch it! Instead, pause the game and restart the level. Now run to it as fast as you can. Since the shards act as save-points, find the next one and repeat. Do this until you have all three.

Free Rings As Tails
Go to any place with grass and look for a dark green weed. Wack it with your tail. If you are lucky, a ring or extra life will appear.

Free Rings Part 2
While playing with Knuckles and have the Silver knuckle gloves, goto a place where you can dig and in most places (especially places with plants) you can uncover up to 20 rings.

Golden Chao Baby
There are two open shops in the part of Station Square with the open manhole. The golden chao's egg is in one of them. Unfortunately every time you lift the egg from its pressure sensitive platform, the doors are barred shut. Go to the city hall area where you fought Chaos 0 and look near the walls and grass. An egg-shaped rock is here, and you can put it on the platform in the store. You may now leave freely with the golden chao egg.

Metallic Chao Baby
To get the one-of-a-kind metallic chao baby, go to the waterfall near the subway and look to the right of it. You will see a sort of platform. Go to it and push it. A metallic egg will fall down the waterfall and into the pond. When it reaches the land pick t up and bring it to the nearest Chao sanctuary. Throw it and it will hatch.

NiGHTS Chao baby
Give your Chao baby 20 different purple animals and it will start to look a character from the Sega Saturn game NiGHTS

One-and-a-Half Play
When you are playing Sonic's action stages and Tails is on the screen, a second player can control Tails with a second controller. Any rings Tails collects will be added to Sonic's totals. Be careful to not make Tails break open any shields, invincibilities or One Up item boxes as those will not be added to Sonic and will be wasted. This feature may seem trivial to most people, but you'd be surprised how much fun it can be trying to outrun player one (who's playing Sonic) when you're controlling Tails. ;)

PC Wallpaper
If you insert your Sonic Adventure game disc into a PC CDROM drive, you will have access to a directory called "extras". Inside you'll find a number of Sonic Adventure desktop wallpapers you can decorate your PC's desktop with.

Secret Chao Puzzle Game
After you start up the Sonic Adventure game, place a controller into the D port on your Dreamcast and have a VMS in the controller. A hidden Chao Puzzle game will appear on the VMS screen. It is a tile based puzzle game where you have to use the Dreamcast's controller to move the pieces of a moving picture around to win. After every five puzzles you solve, a little animation will play on the VMS screen.

Sonic's Snowboard
Select Just before entering the snowboarding part of the ice stage, press X to get Sonic's blue snowboard (previously seen in Sonic 3 and Sonic Triple Trouble). Press B to get Sonic's yellow board (only seen in Sonic Adventure.)

Sonic's Special Super Speed Shoes In the Station Square
Head towards where you first faught Chaos (0.) Instead of going in the park, go to the hole in the ground. Fall in, then follow the path. You will find a rainbow colored area, step in.To get out, speed until Sonic says "Ready?" and keep holding down the speed button. press the button with the star on it and let go of the speed button.

press Start. If you do this with the original Sonic game you can play the levels in order and will be given a password to save your progress.

Note: In case you're wondering, I've left out the passwords deliberately. There are over 32,000 bonus rounds in Sonic & Knuckles. I can't possibly list them
all on the page, nor is there much point to doing so since the levels are nearly identical. Thank you.

Codes - Knuckles Chaotix - 32X

50,000 Point Bonus
When you are able to collect all the chaos rings, the special stage entrance still appears after collecting fifty rings. This time, the stage appears in a wire frame form which makes it harder. Finish the stage and you get 50,000 points!

Cut the Cord
In Botanic Base, it is easier to beat the boss by losing your partner. This gets rid of that annoying bungee mode and you can just hit the boss from the bottom. 

Different Music in Techno-Tower
In Techno-Tower Zone, Acts 1 and 2, go in a bonus stage, then leave. Right when the screen goes from white to the zone, PRESS PAUSE IMMEDIATELY! This will let you play with different music from another Zone for the rest of the act! 

Easy Chaos Rings
Start a game and save through Manual Save. Go through the level and play the special stage. If you win, exit the game at the world entrance to save. If you don't win the Ring, hit RESET. Your loss will not be counted neither will your passing the level. With this, you can have all five Chaos Rings and only have passed five levels!

Playing Tip
When choosing characters it's best to consider what you need for the next level. For example, if you're after raw speed the combination of Mighty and Espieo can't be beat. For power, Hevey and Espieo are your best bet, and for moments when you need both (like fighting bosses) try Charmie and Hevey.

Remove the Bungee code in Marina Madness
In Marina Madness Zone, get rid of your partner. Then quickly find a yellow ship button that will move a ship. Step on it, and you will play without the bungee cord for the rest of the act.

Tempo Control
On the Sound Test screen you can use buttons X and Y to select MONO or STEREO sound and change the tempo of the music.

The credits will appear after Athena is rescued. Punch or kick the credits to force them to scroll downward.

Two-player mode:

Higher jumps:
Hold Up while jumping.

Hint: Defeating the second Boss:
When Nelf turns into the big eye, get close to the middle of the eye when he is still in smoke form. Then use the electricity attack and he will die instantly. Note: You may still get hit while attacking. This trick works best with a controller with a turbo feature.

Hint: Defeating the final Boss:
When you get to the Boss, duck and shoot your fireball. This works quickly and is effective. This is easy, because he uses his arms more than his legs -- he will only kicks with about one in every ten punches. Note: You will still get hit -- jump back and forth if needed.


Columns

Second magic jewel:
Create one row of normal jewels stacked almost to the top of the playfield. Allow a vertical space for only two of the three jewels in the next block to fit.. Watch the preview window for the next magic jewel block. When it appears, quickly move it to the top of the prepared stack. The magic jewel will eliminate the "touching" color jewels, and all of the remaining jewels will drop down, as will the single magic jewel that was off the playfield. This single magic jewel will drop down and eliminate another group of colored jewels.

10,000 bonus points:
Create one vertical column that is empty all the way to the bottom of the playfield. Watch the preview window for the next magic jewel block. Position it in a way so it falls down this column to the bottom.

Create magic jewel:
Begin game play in easy arcade mode. Fill the two columns on the far left or far right as high as possible with jewels to create a magic jewel.

Phantasy Star 2

Slow motion:
Pause game play while in the countryside by holding Start + A. Keep A pressed to move in slow motion.

No opponents in dungeons:
Continuously press B to display the control menu and A to close it while holding the D-pad in any direction.

Hint: Shortcut:
After leaving the second town (the one the bandits destroyed), go west along the bottom of the isle to the side of the tunnel. The side of the tunnel is a secret entrance and saves either a long trip back, or 60M for the teleporter.

Hint: Zema slowdown:
In the town of Zema (a resort town), after the biolab, the people are all tourists or elderly, and will habitually block the bridges and paths in town. Patience is a plus.

Hint: Visit Zema and Kueri at the same time:
Due to the fact that the monsters in and around Zema and Kueri are very similar, the game allows for both cities to be visited at the same time. Use this to get better armor and weapons, get and level up Kain the wrecker, and level up your party twice as much, making the dump tower (Roron ) much easier to defeat.
 

Hint: Easy Ceramic Knives:
When Rolf is at level 5, he needs to level up to go to the abandoned building where the "scoundrels" are hiding. The knives he is using are almost useless. The Ceramic Knives in the second town have a hit value of about 25 points for most enemies, but cost 2800M. To buy these knives, build your characters EXP and M around the abandoned building. The monsters here have a value of about 80 to over 100 M most of the time, allowing the knives to be bought just about the time the characters are ready for the abandoned building. This also allows you to buy Rudo's Sonic Guns and Shotgun.
 Hint: Amy with knives:
Contrary to other sources, Amy can use knives. To best suit her abilities, pair the best knives in the Aria with her best shot weapon. Also use knives until a decent shot weapon becomes available.

Hint: Saving money:
When the doctor charges large fees to heal, go to Paseo (the first town), where the doctor only charges a small fee. You will also be in Paseo if you are using the Visiphone and the Ryuka Technique, or retrieving Shir the thief when she steals something. 

Hint: Stealing items:
When you get Shir the thief and she is leveled up properly (about level 10) take her to shops. When the text finishes appearing on the screen, press B(2) to leave. Repeat this until Rolf says that Shir is gone. Go back to Rolf's house and she will be there, and the item she stole will be in her inventory. Use this trick in the Central Tower in the first city for the Visiphone, and in the second city (the burnt out one) for the Fire Staff. Shir often finds rare items, but you must have patience. She only steals at random, and has a knack for grabbing daggers and other cheap items first.

Glitch: Catman:
Look closely at the Catman on Uzo Island. It is actually a shapely Catwoman.


Revenge Of Shinobi

Unlimited shurikens:
Select the "Shurikens" choice on the options screen and set it to 00. After approximately ten seconds this value will change to an infinity symbol.

End bonus:
Complete any level with a number of shurikens equal to 11 times the number of remaining lives. 30,000 bonus points will be added to your score.


Sega Swirl

Saving the game:
Use the following steps to save your Shining Force game. You wukk get to a point where you talk to a old man in a chapel-like building. This man helps you with your quests. You have four options. The one at the top is "SAVE". There are also "REVISE", "PROMOTE", and "CURE" options. Do not quit the game until you get to this point, or you will lose your game data. After you choose to have the old man save your progress (the game will tell you that it is saving, but it actually does not unless you use the in-game "Save Game" option). To open up the in-game option screen, hold Start and press A + B + X + Y. The in-game option screen will appear. Go to "Save Game" and press A. Do not quit without using the in-game "Save Game" option. To restore your game at a later time, start the game and you will go to thescreen where the girl talks to you.

Hint: Golden Chao egg:
Go to the Station Square area. Then, go to the area when you fought Chaos for the first time. Look to the side of the City Hall entrance to find egg shaped rock. Take the rock to the building to the left from City Hall. Walk to the window to see a golden Chao egg. However, if you try to take it the front door will lock. Replace the egg with the rock and the door will unlock, allowing you to leave with the egg. When the egg hatches you will have a golden Chao.

Hint: Black and blue Chao egg:
Go to the egg carrier. Then, go the jail area where Amy was kept. In the cell next to where she was held is a black and blue egg. Step on the switch to open the door. Take the egg to the garden. When it hatches, it will be a dark grey and dark blue Chao.

Hint: Multiple Chao eggs:
Go to the cell next to where Amy was kept. Pick up the Chao egg and take it to the next room. Drop it down the hole in the middle of the whack a mole game. Go back to the room with the egg. There should be two of them. Pick up the one in the original location, take it to the whack a mole game, and drop it down the same hole. Return to the egg and pick up the one in the original location and there will be one under it. Continue to drop this down the hole and you will get multiple eggs.
 

Get an gold, black or silver egg and hatch it. Then, quit and go back to where you found the egg. It will be there again. You can repeat as many times as desired.

Hint: Iron Chao:
Your Chao must first be evolved. Mate a Gold and a Black Chao and hatch it. Only one out of three eggs will be iron.

Hint: Ruby Chao:
Mate a Dark and Hero Chao. It might take a while, but it will eventually appear.

Hint: Special Chao:
Collect at least 100 emblems to get access to a special section called the Black Market on the Dreamcast Network. A Special Chao can be downloaded from this area.

Hint: Get all five Chaos Emeralds with the Chao:
To get all five of the Chaos Emeralds that you can get with the Chao, you need to log on to the Dreamcast Network and go to the Chao Daycare Section. Download one of the Chaos that are 999 in all four categories. Return to your Chao Garden and race him in a Chao Race. He will leave easily defeat all the other Chao. Repeat this on all five races to get the five possible Chaos Emeralds.

Hint: Finding Emeralds quickly:
Emeralds are always in the same place when you go treasure hunting. Learn where the emerald shards are and you will find them very quickly for the third mission.

Hint: Copy Chao:
Place the VMU with the Chao in socket 1 and the destination VMU in socket 2. Enter the Chao Garden, then leave the Chao Garden. After the "Now Saving" message, look at the data on the VMU. If done correctly, it will have Chao data. Note: The VMU will not have the Chao Game on it. This can be fixed by taking your copied chao out of the VMU, and putting it in the Chao Garden. Then, put the Chao back in your VMU.

Hint: Alternate Chao copying:
To copy a single Chao, you have to have at least one VMU and one memory card. You have to chose the memory card to save your game onto and not the VMU. Go into any of the gardens and pause game play. Then remove the memory card from the controller. Pick up the Chao you want to clone and put it into the VMU. After it is in the VMU, do not put the memory card back into the controller. Instead, just shut off the game so it cannot save it. When you start the game again, the Chao should be in the garden and in the VMU. 

Hint: Copy up to 24 Chao at once:
Note: A mega memory card is required for this trick. Choose the game on the MMC with the Chao you want to copy (all twenty four in the three gardens). Go into any garden and pause game play. Switch the port on the back of the MMC to the game that you want to put the Chaos in. Caution: The copied Chaos will remove any of the other Chaos in the game you switched it to. After switching the ports, resume the game and exit the garden. After it finishes saving, you should turn off the game. The copying of Chaos does not affect the game itself, only the Chaos in the gardens.
.

Hint: Unlimited Chaos:
Get the Silver Egg, the Gold Egg, and the Black Egg. Then, go to the Chao Garden. It will save while you are going in. After you are in, put down the Chao then quit. Then go back into the game and go to the same place that you got that Chao Another egg should be sitting there. Repeat this as many times as needed.
.

Hint: Super Chaos:
There are four special evolutions possible for the little Chao creatures: the Sonic, NiGHTS, Alien, and the Dragon. After giving a normal Chao so many certain colored animals it will evolve into one of these. After the first evolution, keep giving it more of the same colored animals. Its new features will continue to grow. If you give it different colored animals, they will shrink. 

Hint: Keep Light Speed light on Sonic in Chao Garden:
When you are in the Chao Garden, charge up Light Speed until Sonic says "Ready...!" but do not release the button. Go over to a Chao or Chao Egg and press Y to pick it up while still holding the Light Speed button. When you are holding the Chao or Chao Egg, release of the Light Speed button. You can now walk around with Light Speed without holding the button. 

Hint: Sonic The Armadillo:

If you want to get to the inside from the front of the ship, use the monorail or complete the Sky Deck stage. You only need to destroy the capsule. If you want to change the ship's shape again, do it in the exactly same way that you did it in adventure mode. The ship should be its normal shape again.

Hint: Casinopolis: Unlimited rings:
When you get to Casinopolis (level 3), go to the Night Pinball. Try to get five cards. You have to get one pair, two pair, three of a kind, full house, four of a kind, or five of a kind to get rings. Note: This is the best way to complete the level.

With the Gloves, you can do an attack much like Sonic's "Ancient Light", only with Knuckles.

Hint: Mystical Ruins: Extra life:
Tail's workshop is located all the way at the top of the mountains in the Mystical Ruins. Go to the very top and look around to find an extra life. Use the spin attack to zoom over and collect it.

Go left to find an egg-shaped rock Use that rock in the store in Station Square with the Gold Chao Egg in the window. Take the gold one off the platform and put the rock on that same platform and the doors will unlock and open.

Hint: Station Square: Big gets hurt in sewer:
Once you start Big's level, you will end up in Station Square. Go towards City Hall and you will have to pick up a car and go into a sewer. When you get to the elevator, let Big's tail stick out of the door and he will say "Owch!"

Hint: Twinkle Park: Huge bait:
Go to Twinkle Park with Big and start fishing. When the screen says "Hit!", press L + R

Hint: All characters in Twinkle Circuit:
Go to Station Square then go to the entrance of Sonic and Tails Speed Highway. On the side of the building is a patch of grass. In it is a cart pass. It is easy to see. Pick it up and go to the park entrance. You can only go to Twinkle Circuit, not Twinkle Park.

Hint: Easy rings for Tails:
As Tails, fly up and ring the bell which appears around the halfway point of Speed Highway. About 40 rings will pour out of the bell.

Hint: Glide as Tails:
Tails' Rhythm Badge is required for this trick. Go to the Egg Carrier and transform the ship so that the platform where you fought Chaos 6 is there. Note: It could be the other form but it is most likely to be this one. Go down the hill behind the large wall until Tails rumbles and will not go any further. Then, face the way you came and hold down a Tail Whip. Go up the hill at full speed, still attacking, then when you go over the top Tails will glide using the Tail Whip for a while.

With the shield, go upstairs in the hotel and stand on the button that creates rings for Sonic to get his power-up. The rings will continue to replenish after being drawn into the electric shield. The rings will keep appearing until you have 999. Note: Getting the shield may take some time.

Hint: Knuckles in Sonic's Lost World:
Do your part of the stage by taking Sonic's route through this place. When you find the room with a hole going down and some rings, climb down until you find the bomb's capsule. Activate the bomb, then in that same place keep jumping until Knuckles goes through the ceiling. Note: This may take some time. When you finally go through it, you will notice that there is no ground, so glide instead. When you get to the building, try finding parts of it that you can go through. It does not matter which one. When you do find one, it should look familiar. You are in Sonic's Lost World.
.

Hint: Easy coins and lives for Big:

Glitch: Giant characters:
Go to the Mystic Ruins as any character. Walk on to the platform by the train. Jump on the train and have your character face the sea. Rotate the view so that the character is facing you. It now should appear as if the character has grown to immense size on the platform.

There is a way to skip the loading time on the stairs on the docks at the Egg Carrier. First, go to the dock. Angle Sonic so that he is on the opposite side from the boat. Then, jump diagonally on to the stairs and keep jumping up to get to the top. For fun, jump off the stairs to see Sonic float for a bit. You still cannot get to top because of loading time, so jump diagonally onto the Egg Carrier.

Hint: Chao raising:
First, get all the animals you want for your Chao. Make sure that you get the Chao you want it to look like. Then, stop and collect Chaos drives only. Chaos drives are the same as animals, but they do not change your Chao's appearance. Chaos drives are the thin pieces of machinery that fall off of the G.U.N. machines when you destroy them. This way, you can get your Chao to have good stats without having to worry about a good feature being bumped off. Note: Yellow is swimming, green is running, red is strength and purple is flying.

Hint: Omochao loses his propeller:
This trick cannot be done with Tails or Eggman because their walkers have no hands. Using any other character, pick up Omochao and throw him off a cliff. It may take a few seconds, but Omochao should reappear without a propeller on his head.
.

Hint: Omochao hurts himself:
Use the following trick to get Omochao to hurt himself in the Pyramid Cave, Death Chamber, Egg Quarters, or Sand Ocean level. Activate an Omochao and go under one of the flames. Since Omochao flies above you, he should hit the fire and take a hit. He will get mad at you afterwards.

Load Sonic Adventure, then go to the Chao Garden where the Chao you want in Sonic Adventure 2 is located. Put it into Chao Adventure. Load Sonic Adventure 2 and go to a Chao Garden. Go to the transporter. On the VMU with Chao Adventure, there should be an egg. It is the egg for your Chao from Sonic Adventure. When it hatches, it will be back to its first form. The only thing transferred is the name, but the Gold Chao will be gold, the Silver Chao will be silver, and the Black Chao will be black. Note: If you pet or try to influence the Chao you imported, it will lose it original colors.

Hint: Black Chao:
To make a black Chao, grab it and keep throwing it to the ground or the walls.

Hint: Black Bull Chao:
Hit your newborn Chao twice, then give it two sheep until it gets the horns. Next, pet it with a dark character until it becomes a dark Chao. Then, give it about ten Green Chaos Drives and wait for it to evolve. Keep petting it to make this go faster. If you Chao still crawls, give it two animals that walk on two legs, if it loses its horns, give it a sheep. Once it evolves, hit it three times with a hero character. Then, using a dark character, ignore it and do not feed it for thirty minutes (you must be in the Chao Garden). Then, hit it again until it starts to have a angry face and makes angry noises. It will start to charge around like a bull and chase the other Chaos around the Garden . If you want to stop you Chao from doing this, keep petting it with a hero character. If you want it to go back to bull mode, wake it up when it is asleep by picking it up.

Hint: Super speed:
In two player mode, use a speed up then wait for the little blue light to disappear. Then, get the Super Shoes. The easiest way to do this is to play Shadow's Bridge level.

Hint: Alternate jump:
While running, do a somersault, then jump anytime during the somersault.

Hint: Better sharp turns:
Use the following trick to make sharp turns when playing Tails or Rouge or when trying to get Emblems in the Kart Racing mini-game. When you are about to make the turn, release A for about a second and a half. Move in the direction the turn is going in, and then press A again. This should make the tires skid. If you do not turn for awhile however, this effect will wear off and you will need to do it again. This is almost required when going for Rouge and Tail's fourth mission in Kart Racing, "Do not touch the walls." Note: When you do this, you car loses a bit of its top speed. Release A and then press it again to reach your maximum speed once again.

It will shut off automatically when you jump.
 

Hint: Sonic: Extra points:
When playing as Sonic, use the special punch attack after hitting and destroying an enemy to hit another and collect more points.
 

Hint: Sonic or Shadow: Mystic Melody:
The Mystic Melody for Sonic and Shadow is in their final stages. For Sonic, keep playing through the level until you see a rocket on a platform while grinding on a rail. Jump to it, and use it to go to a different route. Keep playing through this route until you get to the Mystic Melody. For Shadow, there is one part of the level where you can keep spiraling up on magnetic tubes. Eventually you will get to the Mystic Melody. The Mystic Melody is a tool every character can get.

Once you get the Fire Somersault Bracelet, return to the first level of Sonic's adventure (City Escape). Go towards the end of the level and look for a spot on the ground composed of four steel crates. Perform the bounce attack on top of them and you will fall into a secret room. Once there, you can bounce and destroy more crates to find the Magic Gloves. They will allow you to turn an enemy into a miniature throwable version. However, you have to get very close, making it not all that useful.
.

Hint: City Escape: Unicorn animal for Chao:
Play the level as Sonic (the first level of the Hero story) and get the three Chao boxes. The first Chao box should have a Chao key in it. It is at the part (to the right) where you go upstairs.

Hint: Crazy Gadget: End of level:
As Sonic, reach the last sequence when you hit the switch before you get the goal to launch the missile. Use the first switch then instead of using the second switch. Use the bounce attack to go higher to the red platform and move to your left. Hit the switch to go down. Step off the purple platform to find the switch. Use the bounce attack to get high enough to reach the gravity switch. Once you do, just jump to hit the switch. The next part is tricky. Use the homing attack to hit the spring near the goal and do not press anything. You should end up back where you started use the first switch to go up. Repeat the procedure, except use the switch that is straight ahead. When you get down, fire the missile to get the goal.
Hint: Egg Quarters: A rank:
To get an A rank for Rouge in Egg Quarters, get the three keys in 4:30. Usually you have to get it in 1:30.

Hint: Final Rush: Extra lives:
As Sonic, after the first grinding rail, land on the first platform. Take the lower of the two rails. At the end of the rail, jump to the platform and use the only rail, on the ground. At the end of that rail, there is a platform with speed panels. At the end of the platform there is a bomb robot over another platform. Destroy it and use the rail off of the platform it was over. At the end of that rail is a check point with a small gap afterward. Jump the gap and go all the way down the big drop. At the bottom is a rail on the left side. It will take you to a platform with a ring box and a life box. Get the life and then choose "Exit" from the "Start" menu. Re-enter the level and you should have the same number of lives you had when you exited the level. Repeat this as many times as needed.

Hint: Hidden Base: Interesting statue:
In the Hidden Base level as Tails, go to the pulley where, at the top, there are five to six Kiki's throwing bombs at you. In that area is a headless statue of a nude woman, holding her cleavage.

Hint: Hidden Base: Green sea monster Chao:
When playing as Tails, there is a hidden green sea monster Chao in the small maze. It makes your Chao's color turn green. 

Hint: Iron Gate: Special Dragon Animal for your Chao:
To get A Special Dragon for the Dark story line, get all three Chao boxes in Iron Gate as Dr. Eggman. Be careful 00 one of the boxes is near the goal,
.

Hint: Iron Gate: Laser Blast:
First, find the Cannon in the Weapons Bed level, then play the Iron Gate level again. Go to the location where you find the most coins and two gas pipes. Blast those gas pipes. You will now see a way leading to a hall. The Laser Blast is inside, glowing green light. Take it. It makes it easier to lock-on to more opponents. 

Hint: Mad Space: Phantasy Star Online items:
In the Mad Space level as Rouge, you can find items from Phantasy Star Online lying around -- the boxes rather not items themselves. For example, you can find green and blue boxes from the game.
 

Hint: Metal Harbor: Shortcut:
Near the beginning as Sonic, after doing the loop-de-loop there is a robot you can home-attack, which will take you to a faster route. After completing this much faster route, simply finish the rest of the level as fast as you can without taking detours. Also try to go straight all the way on the street board at the end-- do not zig-zag.
 

Hint: Pumpkin Hill: Ghosts:
As Knuckles, from Pumpkin Hill to the rest of the game you can find ghosts in certain places. Note: They just pop out and knock you down.
 

Hint: Pumpkin Hill: Extra Skeleton Dogs:
As Knuckles, go to Pumpkin Hill and get the extra life that is buried where the Shovel Claw was located. Then, go to Church Mountain and look around one of the graves closest to the wall. You should find a Skeleton Dog there. Restart the Level and do the same thing over again until you have as many as needed. The last time you do that, find a Chao Key and finish the level. It is easier to do this if you are on the 100 Ring mission or the Find The Chao mission.

Hint: Pumpkin Hill: Safe from fall:
When you fall for a while, glide then do the Spinning Dig move and hold it down. You will bounce back up and be able to glide to safety. If you do not make it, repeat until you do.

Hint: Pumpkin Hill: Early lives:
When starting Pumpkin Hill as Knuckles, go to the left rocket that takes you to Church Mountain. Then, take the rocket that leads to Pumpkin Mountain, which is somewhere in the graveyard area. While falling down from that rocket, quickly glide forward to the flying "island" in front of you. If done correctly, you should grip to the floating chunk of land and be able to go forward to get the extra life. This can be useful for people who are collecting Skel-dogs, because you can get it in the graveyard place before you take the rocket. There is also an extra life buried where the digging claw things used to be -- so this can double as an unlimited lives trick. Note: Skel-dogs are useful for people who are raising running Chao because they remove the boar's ugly features, and provide a running improvement of up to 16, without subtracting from other stats.

Hint: Radical Highway: Fire Ring:
As Shadow, after the second highway you spring to, go backwards instead of forwards. You will see a rollie object that you need to somersault through to a new route. The new route leads to the Fire Ring that allows you to break steel crates. Note: You need the Light Shoes or you will not be able to get it.
 

Use the following trick to get the Fire Ring without using the Light Dash. When you get to the row of rings in mid-air on the path to the ring, simply somersault at Super Sonic speed. Press A while holding the D-pad in the direction of the rings. You should be in mid-air. Press A again to use the Homing attack. You will hit the spring and get the ring.

Hint: Radical Highway: Got Ring? Blimp:
There is a blimp with the message "Got Ring?" in the level.

Hint: Radical Highway: Lost Chao location:
Note: You must have the Mystic Melody to find this Chao. Go to the part where there are two loops. At the end of the loops (next to the speed ramps), jump to the left ready to attack and hit the spring that is down there. You cannot see it at first, so be careful. 

Hint: Security Hall: Fast completion:
In this stage you play as Rouge the Bat and are given 5 minutes to complete it. This can prove to be quite difficult. If you have enough lives you can do this trick. If you cannot seem to find the Emeralds, you should die. You will keep the existing Emeralds that you have collected. You will begin at the start of the level and the Emeralds will move to different places. This is the fastest method for completing the level if you are having trouble.
 

Hint: Security Hall: Cut through lasers without losing rings:
As Rogue, get a running start and glide as fast as you can. If you are quick enough, when you touch a laser you will hear a spark but will not get hurt. You can only do this on lasers that are high. This is best done in the higher room with the switches.

Hint: Security Hall: Alternate shield color:
Play as Rouge in the Security Hall under the hard difficulty setting. The shield robots will be holding black shields instead of red ones.

Hint: Sky Rail: Shortcut:
There are places in the level where you can jump as Shadow from the rail you are on to a rail you are going past that you normally would not get to until later in the level. This method saves time, and it is fairly easy. Be careful -- do not jump to a rail that will take you back, adding time. Additionally, on the last rail, take the rail on the right versus the left. The one on the right slopes straight down to the goal. Also, crouch at the very beginning to go much faster.

Hint: Sky Rail: Find the lost Chao:
The Mystic Melody and Light Speed Dash are required. At the second checkpoint there will be rail. Do not go on it. Instead, turn to the left and you should see the Mystic Block. Play the Mystic Melody and rings will appear. Do the Light Speed Dash and there will be a lot of bouncy things. Bounce up a few and at the top you will see the lost Chao. Go up a few more bouncy things to reach it.
 

Hint: Sky Rail: Ancient Light:
As Shadow, skip the rocket and use the spring. Hit the bouncy propeller object until you get to the limit. You will see an enemy robot that you need to kill. Following him is a string of robots that you attack until you get to the Ancient Light for Shadow. It does the same thing as the Ancient Light for Sonic.

Hint: White Jungle: Ancient Light:
To get the Ancient Light from the original Sonic Adventure, go to the White Jungle level as Sonic and keep playing until you reach the part where you are in a tree with many enemy robots. Jump up to the area with the box of rings. From there, walk to the edge of the platform until you see an enemy robot. Home attack it and keep going, attacking item boxes until you get to an extra life at the end of the line. There is also a 1-Up item which is the Ancient Light. 

Hint: White Jungle: Fourth mission Emblem:
There are no shortcuts in this level. To get the Emblem as Shadow, keep running and do not get hurt.
 

Hint: White Jungle: Easy points:
When playing as Shadow there are two places where you get points for easy things. At the very start of the level, after swinging on your first vine, somersault under a fence for 500 free points. Then, when you are in a grassy area much like the area where Sonic gets his Ancient Light, instead of going the short way which leads to invincibility, somersault under a gate behind two robots. Dodge the sparking robot and when you reach two robots, one flying around one just standing, hit the flying one. Stay in the air as long as you can and bash the second one to get the usual 100 points, but you will also get 400 bonus points. 

Hint: Wild Canyon: Special Dragon Animal for your Chao:
Play as Knuckles in the Wild Canyon level. Get all three Chao Boxes. The first Chao Box will be the Chao key. When you get the second Chao Box you can get 2, 3 or 4 animals. With the third Chao Box, you can get the Dragon. 

For an easier way to get a Dragon, start the Wild Canyon level and go to the place where you get the power-up on the wall you came out of. Look to where it and the left wall intersects. Climb up to find a Dragon. Go over there and play the Mystic Melody. Go forward and get the extra life. Restart and do it again.

As Knuckles go to where you find the Mystic Melody. The little Dragon should be in the rear left-hand corner.
 

Hint: Wild Canyon: Extra dragons and lives:
Use the following trick to get a lot of dragons in about ten minutes. At the start of the Wild Canyon level, climb the tall pillar to your right. When you reach the top, get the extra life and glide to the pillar on the other side of the room. Then, glide onto the pillar closest to it and get the Chao box. Enter the "wind tunnel" and when you get to the top, go to your left. Go to one of the first cubes blocked by boxes. Punch the boxes for another extra life, then go to the end of the path. Once there, hit the Chao box, but avoid the animals. Once you get that, go to the path across from the one you that are in. Go all the way down and either kill or ignore the rhinos. Then, drop down into the statue area. Get the Chao box and the dragon, then exit and repeat this as many times as needed.
 

Hint: Defeating Big Foot:
In the Hero storyline, you can defeat Big Foot faster by jumping on the wooden boxes. From here, you can attack him without having to wait until he lands. After he shoots out all the boxes, defeat him the standard way.
Information in this section was contributed by MonkyFun.

As Sonic, if you have the bounce attack, just bounce around Big Foot.

Hint: Defeating Eggman:
In the Hero storyline, during both battles with Eggman forget about the lock-on missile -- it is too slow. Instead, rapidly attack him with your Vulcan cannon.
Information in this section was contributed by MonkyFun.

Hint: Defeating Egg Golem:
Beside climbing the stairs on Golem's back, you can hit him another way. You can only do this when he has two or less hits remaining. When he uses his head butt of death, stay to the side of his fists so the head misses. Then, get directly under the head. He takes a few seconds to pick it up again -- use a bounce attack to hit the "battery".
 

When fighting Egg Golem, fall down to the sand pit area and land on the platforms. Then, hang on to the rope that pulls you up. When you are up do not get off the rope. Remain there and shoot Egg Golem. When he does his head butt, quickly jump back down on the platform then repeat until he is defeated.
 

Hint: Defeating King Boom Boo:
In the Hero storyline, only run fast enough so you can see his face. When he starts breathing blue fire, you will have more than enough time to punch the ghost holding the hour glass while he is preoccupied making is wall.
Information in this section was contributed by MonkyFun.

King Boom Boo as one attack called the Chomp Attack. Be careful, because he also speeds up when he does it. If you slow down, quickly speed back up or he will speed up and attack.

Hint: Defeating Shadow:
In the Hero storyline, during both Shadow battles you can use the same strategies. Shadow cannot defend against the bounce attack.
Information in this section was contributed by MonkyFun.

Instead of trying to catch him off-guard, keep somersaulting at him. This makes the battle easy.

Hint: Defeating Sonic:
In the Dark storyline, instead of trying to catch him off-guard, keep somersaulting at him. This makes the battle easy. 

Hint: Defeating Sonic or Shadow:
This trick works for either character during the final battle. When fighting, fall behind of your opponent. When you are far enough, he will do his special attack. Quickly do the homing attack to avoid it. If you are fast enough, quickly do the homing attack at your opponent and you will hurt him. You need to do the homing attack very quickly, or he will start running again and you will not hurt him.
 

After you complete the last level on the Hero storyline , you will have to battle Shadow. The first three hits are easy. Just to get up close to him and use your Homing Attack. The last two hits are fairly difficult. If you use the Homing Attack, he will also do it. so it wont hurt him. Press the Analog-stick slightly so you are walking, not running. You will get left behind. After about two seconds, start charging up your Spin Attack with B. When they use their attack on you, release and aim for Shadow while spinning. This trick can also be used when facing Sonic as Shadow.

Hint: Make Omochao angry:
Pick him up and throw him around. If you throw him at an enemy, he will explode. You can even shoot him with Eggman or Tails while he is flying around your head.

Hint: E102 appearance:
In Rouge's Inside the Pyramid level, one of the robots you blow up is E-102.
 

Hint: Character comments:
While playing as any character, stand in a place for a while and your character will comment about the stage. Some examples are:
Sonic in Crazy Gadget: "This place is a real pain in the butt!"
Knuckles in Pumpkin Hill: " This place sure feels haunted."
Shadow in Radical Highway: "I sense danger all around me."
Sonic in City Escape: "This city sure has some steep hills."

Glitch: Stuck in wall:
As Sonic or Shadow, enter the regular Chao Garden. From the entrance walk right against the wall while pushing against it with your side. If done correctly you will walk into a little groove in the wall. You will do the spin attack even though B was not pressed. Note: Be careful because you may hit your Chao. 

Glitch: See through walls:
Press L or R in certain places and you can see through the wall. Try this as Knuckles at Pumpkin Hill at the train area.

Glitch: Fall endlessly in Final Rush:
While as Sonic running away from the burning rocks in the last part of Final Rush, run at full speed and make sure you do not get hit by the rocks. Then, jump to your left or your right, whichever you are closer to. Hold A to make a full jump and then press the direction that you want to jump off of. You will notice that you just jumped over the barrier. You will now fall endlessly to your death. However, if you got hit by one of the rocks on the way out, there will be a strange aura attacking you as you fall. You may die before you reach the atmosphere. 

Glitch: Invisible snowboard:
In the Metal Harbor hero level, press Y on controller B. Sonic will be snowboarding, yet will have no snowboard under his feet.

Glitch: Invisible ledge:

Glitch: Get the Air Board at the start:
To get the board early, press Y on controller B.
 

Glitch: Wrong camera angle:
In the City Escape level as Sonic, find the part near the end with an under-pass that you need to somersault under. When you do that, quickly jump. If you are lucky, the camera will be in the other direction, showing you where the ramp's and speed things are located. This may require multiple tries.

Glitch: Frozen Shadow:
Shadow's Ancient Light is required for this trick. Once you have it, go to the Final Chase level. When you meet your first shielded robot outside a tunnel, stand as far from it as possible and use Light Attack. Shadow will go to the top of the roof and freeze in the Spin Dash position. Unless you press B, he will continue to be that way.

Glitch: Frozen Sonic:
Sonic's Ancient Light is required for this trick. Once you have it, go to Pyramid Cave level. Use the Light Attack on the fourth gamma robot from the Bounce Bracelet. Sonic should destroy the robot and stay in one of the corners, frozen in the Spin Dash position and flicke. Press B to revert back to normal.

When you get Sonic's Ancient Light, go to the Crazy Gadget level. Proceed until you get to the last checkpoint near the door to the boxes room. When you get in the boxes room, intentionally die. You will appear to be back at the last checkpoint. The door behind you will be shut. Stand directly next to it and use the Ancient Light. You will be frozen unless you press B.

Hint: Keep special colored Chao:
To keep the special colored Chao from Sonic Adventure, hatch it first, then take one of those and put them into Sonic Adventure 2. It will turn back to normal during re-entry to the Chao Garden. Once it breeds, the baby will be the original color of the special colored parent.
