Sonic Adventure Refrences
I've ben waiting MONTHSSSSSSSSSSS for some one to do this but it's time I do it myself. There is things from Sonic Adventure/DX: Directors Cut.
1: The first level of Sonic's episode is when you're being chased by a Killer Whale on a wooden track.
2: Eggman's ship is the Egg Carrier. It just has a few adjustments.
Sonic Dies
In the Last Episode Sonic Dies! He was killed by Mephiles. His whole plan was to kill Sonic so Elise would cry. If Elise crys than Iblis will be sent free! Thats why Mephiles wanted Silver to kill Sonic! If Mephiles fuses with Iblis, than they will become SOLARIS! I'm not telling you any more about the Last Episode. Let's just say that you'll be happy in the end....

When you buy a gem at the shop they give you special abilaties. To activate one, use the D-Pad's < and > buttons.
Very fast Sonic
In Multiplayer mode in any level or match, equip the Red Gem on Sonic, activate it and hold it, then die. While still holding the activation button, wait until you respawn. When you respawn, deactivate the gem. You will now run much faster than normal and the time will automatically be slow.
Very High In The Air
At the checkpoint just before the you meet the whale, you should be on a mountain. Jump and turn around when you are past the checkpoint and use the Sky Gem. Turn the camera until you can see Sonic directly. Release R1. If done correctly, Sonic should go very high and he should be in 'space' or a black screen with only the sun showing.
