WEIRD ITEMS
Have you ever noticed some weird items that you can't do anything with. Some items I've found are: bombs (THEY EXPLODE!!), skulls, green, blue, and orange item boxes from PSO, game boxes of old sonic games, and even an X Box!!!!!! Actually I'm not sure its an X Box but its a black box about the same size and shape of an x-box, and it has a green X on it that looks EXACTLY like the x-box's logo. The PSO items can be found on the ARK on Rouge's last stage, and the X-Box can be found in Sonic's CRAZY GADGET stage (the x-box is on an x-shaped floor but look carefully because it blends in with the floor)

Unlock Kart Racing(the real way)

To unlock Kart racing get to the level where Tale's has to chase the president's Limo complete it with in the given time and you will unlock Kart racing

Extra time on rouge level

ON the level where rouge must find 3 choas emeralds within 5 minutes.  If you find the first 2 and only have about a minute of time left....let rouge die and when you start your next life you'll still have the 2 emeralds and about 3 and a half minutes on the clock to find the third

Switch characters in "Final Hazard"

When you play as Super Sonic and Hyper Shadow and you are running low on rings ( When ever you play as Super Sonic or Hyper Shadow, you'll slowly lose rings.) and don't think you'll make it in time to hit the lizards weak spot, then all you need to do to switch to the  other guy, (If your Sonic You will switch with Shadow) is to go to the other side of where you started. Then when you do switch, the other charcter should have about 40 or more rings to start out with.



Get Eggman's Protection Armor

It's at Cosmic Wall.

On the platform there should be a missile. Press the green button to activate the missile, for it to launch to and break those steel cages on the right of you. Then hover to that platform and there should be the protection armor there.

Secret  passage in final rush

In final rush ,do you grind around the rail in the big tube? Well there is another way to do it. When your grinding inside ,jump off but don't panic! Try to grind the rail, if you can.

Mystic Melody for Rouge

On the Dry Lagoon Board when you start, scale the walls in the middle level of the Oasis you start out in. You should find a wall hidden in the shadows that you can dig through that looks different from the others. It has a huge bird on it and it looks like there is an oval shaped portal in his belly. The wall looks just like the ones Knuckles can dig through. Go through and there it is.

Choose chao color

When you are in the normal chao garden (not the light or dark gardens) if you pet your chao with a dark character it will slowly turn darker and if you pet it with a hero character it will slowly turn lighter         NOTE: you have to pet the chao many times in a row for the color change to take place

Exactly what you unlock when you have 180 emblems

I've read through the cheats for sonic adventure 2, and quite francly, i think i'm the only one who has fully completed it, so i've decided to tell you exactly what you unlock and what you don't, and don't say "well i've completed it in a different version and my cheat does work" because i've completed it in jap, eng and amer.

Once totally complete with 180 emblems you unlock the final stage in stage select (if for some reason it wasn't there before), you also get green hill in stage select (it will appear with a question mark on the left hand part of the map, and finally you unlock these characters in 2P mode:

in place of

shadow   = shadow(2) and metal sonic
sonic    = sonic(2) and amy rose
eggman   = eggman(2) and big the cat
tails    = tails(2) and a chao
rouge    = roug(2) and chaos
knuckles = knuckles(2) and tikal

Easy  Way To Beat The Rock Head Dude

All right this is very simple.  When you get around the big rocky dude when he stops and there are the walkways on his back, Do not use your bounce technique, Because when you do that it forces you to go down really fast.
The best way to beat him is just to jump on the stairs.  Another thing, If that little blue robot tells you that you should use the bounce technique because its the easiest way to get to the top, Then he is wrong.

Full Pause

To get pause mode without the pause menu, press X + Y.

Some Powerup Locations

These are the harder to get powerups and are not the ones that are required to complete missions.

        Sonic   Ancient Light
     In the green forest there are two cave -like areas where the bottom has enemies and the top has an exit. In the second cave from the right of the top you can see a ring container. Double jump it  and jump again th find the ancient light.

        Tails
      At the end of his first level there is a passageway you can oen using the bazooka powerup. inside is the homing missle upgrade

        Shadow
      A little into the level there is an area where you take one of those lift things up to a platform with a line of rings leading to an enemy and a spring platform. Jump up the spring platform to the road above.  STOP.
Look for a platform to the left. On it is the fireball attack.



Rouge's emerald finder

You will need mystic melody and metal boots to find this. In Rouge's level where you have to find 3 chaos emeralds you should find a bit of old ruins on the right hand side of the lower part of the room. Play mystic melody, cross over on the platforms, break the two metal containers, break the other two containers and it should be there

Hints for Pumpkin hill on HARD

Are you stuck on Pumpkin Hill on hard? Well here's the solution.
 
 This is much harder than the 1st mission. From the start, go to the right. Look out for the ghost. Hit him 3 times, or jump over him. Take the rocket up, but grab the wall. Head down as far as you can. Then, Jump and glide. You will see the emerald above the spiny balls. If you're lucky you'll get it on you're first try. If you don't, go back to the bottom of the mountain and jump again. The second emerald is on Pumpkin Mountain. Go around untill you find the ledge with the two skulls blowing fire. You will have to climb the wall where the fire hits. Dig. You should find the next emerald. The last one is hard. Go to Church Mountain and climp to the top of the church. Keep trying until you get a view of the sky. Pause and hold Y & X together. See the green sparkle? That's the emerald! Now for getting it. Go to Pumpkin Mountain. Find the spring behind a metal wall-like structure. Bounce and glide toward Church Mountain. You should be at the same height as the emerald. Keep tr!
ying until you get it.
Huh? Looking for the lost Chao? Well, first snag the Mystic melody from the picture in Wild Canyon. Then, go to the top of Pumpkin Mountain. See the weird box? Use Mystic Melody on it. Take the steps to the top. There he is!

This

Knuckles' Snglasses and Shadows ancient light

When you go to Meteor Herd, there is an area with a force field in front of you. Right under that area area several dorrs with red lines on them. There is a floating island not too far fromone of the doors. Punch it as hard as you can and it will break the door. hit the switch inside. now go to the area inside the force field( where you fight Rouge.) the ground should be opened and the glasses are down there.


For Shadow, go to Sky Rail. when you see the very first rocket, don't get it. jump and destroy the enemy toget to the other side. hit the spring and go forward. you will see a thing that goes up when you jump on it. once it is at the top, use the homing attack towards the screen and keep jumping. there is a line of robots that will take you to the ancient light. be careful, the enemies electrify after a while.



Get Shadow's Flame Ring(realway)

In the radical highway, the airplanes will attack u in certain places.
on the second airplane attack, stop!
look back n use somersault to squeeze through the platform.
use light dash to zoom across the way n it should be there.
NOTE:the flame ring lets u do fire somersault. You can use it to break steel containers.

Easy 3rd emerald

The 3rd emerald on Pumpkin Hill(Hard Mode)is ontop of the church. The way to get it is to climb to the very top of the church and stand on it(you can do this)then put Knuckles' sunglasses on. A spring will appear under you and bounce you right to the emerald!(NO GLIDING NEEDED)

Easy Way to Beat Rock golem Quickly

 O.k. Youve beaten rock golem 3000000 times. now heres the way to do it quickly. you know that theres these things that glow on the sairs to his head? wll do dash on to those and you do that all the way to his head. but do it all at the same jump but not dash.

Turning Chao Evil

A easier way of turning chao's evil than petting them and raising them with evil characters is to punch, kick and hurt your chao. If it starts crying hit it some more and it will turn darker and darker until it is black. Then when it evolves it will be evil. Also when you have both evil and hero chao's you open up evil race and hero race in chao stadium.

Chao Pillow

To give a sleeping Chao a pillow, shake a nut of the tree, and set it next to the Chao's head. The Chao will scoot back and use it for a pillow.

Beat the BioLizard

To beat the BioLizard with Shadow, collect the first 7 rings, then run away from him. Once he starts panting, then you jump and use the Homing Attack to do an unbelieveably fast grind up the pipe coming out of it's mouth. It will get angry and start to shoot out electric egg-like balls at you. Just jump and dodge them and attack again.

NOTE: ONLY GRIND ON THE PIPE WHEN IT IS LIGHTING UP.

Be Like Ash
To be like Ash from Pokemon, get the MAGIC GLOVES from the City Escape level. Then, once you come out of the hole, there will be a WalkerBot in front of you. Get directly under it and change the action to Magic Gloves. You can then capture him in a clear "Poke-Ball" like object, and throw him at other enemies and it will blow him up!

Use chaos control on Last Stage Story mode

Ever wish that you could make those stop clocks last just a little longer? Well, theres a way. When you are using Tails/Eggman, you can do it in possibly three (3) different ways:

1. Aim at the clock, then touch without letting go of the button (it should work for about five seconds more than normal.

2. Aim and repeatedly fire at the clock quickly, after about so many times immeadiately hold the button and run where you need to go and hope it works.

3.Same as number three, but rotate the control stick

I still haven't found a way with Rouge/Kuckles yet.

With Sonic, this is the easiest to perform.
When you come into the room that leads to the two walkers, and the floating chaos guy, use the magic gloves on everybody. Once you get to where the clock is, get Sonic ready to perform a super Sonic Spin dash. Hit it at full speed, and the Chaos Control effect should kick in right about...now! If it doesn't work here, use it on the clock just before you go down the big red tube and 'Botnik tells you that it's all up to you. This makes everything easier, especially on the third mission.

The levels to find power ups on.

Sonic:
City escape
Crazy Gadget
Pyramid Cave
Green Forest
Metal Harbour.

Tails:

Stay alive for a longer period on Tail's and Dr Eggman's stage's.

When you are getting hit when you are Tail's or Dr Eggman and your bar at the bottom of your screen get's lower and lower if you want it to regain energy all you need to do is collect a lot of ring's and every ring is about this big =<> so if you collect a lot of ring's your bar will eventually be full.

Space suits(hidden costumes)

If you get an A rank in sonic/tails/knuckles/shadow/robotnic and rouge's missions they will have on a space suit or their robot-car they drive will be different color than normal.

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.

Defeating Shadow:
In the Hero storyline, during both Shadow battles you can use the same strategies. Shadow cannot defend against the bounce attack.
Instead of trying to catch him off-guard, keep somersaulting at him. This makes the battle easy.

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.

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.

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.

Homing Laser upgrade:
To get the Homing Laser upgrade for the Eggwalker, on the first stage of the Dark story line, find a hall blocked by iron containers. Shoot them with your Vulcan cannon (needs to be upgraded first). You will find the homing laser upgrade at the end of the hall.

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.
