Sonic Jam

Remove Pause Box from Robert Hencke
At any pause point (whether Sonic World, Sonic 1, 2, 3, etc..) press X+Y+Z to remove the pause box from the screen.

A New Challenge from Hypersega and Craig Root
Highlight "Sonic World" at the title screen and press and hold A and Start, you'll be dropped into Sonic World with a new Time - Attack mode. You have to get EVERY ring (100) in 60 seconds. This is Extremely hard it took me an really long time to get, but the secret is worth it.

Movie Trick from Scajman and Robert Hencke
To play the movies one after another simply choose the first one and hold X until it starts. The movies should play one after another.

CD Extras from Rael
On the Sonic Jam CD there are a lot of little extras accessible by PC owners.

In the root directory, you can load some of the .AVI files and hear the music.

In directory: D:\extra> There are two subdirectories, one for 16.8Million Color .BMP files and another for 256 Color .BMP Files, all make slick Windows Wallpapers.

In directory: D:\MAN_ENG1> thru D:\MAN_JPN4> There are all the files for the in-game manuals. All images of the pages are in .TIF format, and should all be viewable thru any decent graphics program.

In directory: D:\SONIC12> There are multiple sound clips from the various Sonic games in .AIF format, easily played with the RAPlayer included with Netscape, or standard sound on a Mac.

Make Sonic Walk In The Air from Pascal "Saturnman" Vellet
First, you must complete all the tasks in the Sonic world and see the credits. Once this is done, go to the gallery house. Then use one of the palmtrees as a stepping stone to go on the roof. Press X (your new camera angle after you finish the game) and start walking. Presto! You're walking in the air. Actually, this is more of a bug because it is an error in perspective (something Z-buffering could solve). By the way, you have something similar in Nights when you walk atop a waterfall (Spring Valley).

Trick for Sonic 2 from Justin 'X' Townsend
Sonic 2(Part of Sonic Jam). On the title screen (Any time, either when the animation is doing its thang, or when the game options are available) press Up, Down, Down, Down, Up to hear a ring sound. For some reason this changes all the places where it says 'Tails' so that they now all say 'Miles'.
