A port of the Xbox 360 port of the PC port of the GameCube port of the Dreamcast original.

Unused Sonic Adventure Graphics
The Steam version, unlike the Xbox 360 and PlayStation 3 versions, is simply Sonic Adventure DX, rather than Sonic Adventure with optional Sonic Adventure DX DLC. However, the resources for the original title screen and menus still exist, they simply changed the code that checks for the DLC to always return true.

To reactivate them, change the byte at from 1 to 0 with Cheat Engine. Unfortunately, the game does not function properly like this, the title screen does not respond to the Start button, and menus often think you are selecting something other than what you are.
