Fighting Vipers

This is only partially official. While this isn’t a mod, Sonic and Tails are only playable by modifying the code for the game – they were originally in the game, but were removed at some point (with the data being left in). The developers possibly didn’t have full authorisation from Sega to include the characters, but the creation of Sonic and Tails in Fighting Vipers likely led to the creation of Sonic the Fighters, using the same engine.
