Sonic Heroes Chess
Sonic Heroes Chess is a hack of Super Mario 2 Chess released in circa 2003 by unknown Russian developers. The hack uses a digitalised version of Sonic Heroes' title screen but with "CHESS" added below it. Of course, the game replaces the Mario characters with ones found in Sonic Heroes. The music is a digitalised version of the Egg Albatross theme, however it has been shortened to just 10 second loop.
