Sonic the Hedgehog [ROM Hack] (Super Nintendo)

A hack by Peruvian sceners Twin Eagles Group, released in cartridge form with their permission.

The hack itself replaces Speedy Gonzales with Sonic and the imprisoned mice with Mario. There is some voice acting in this hack, recorded by the hackers themselves to replace the voices in the original game, with Mario yelling "Mario!", when he's rescued and Sonic yelling "Sonic, Sonic!" when he picks up speed shoes. Mario works as a checkpoint, just like the mice in the original game. The cheese pieces have been replaced with rings, although Sonic has a health meter as indicated by the hearts at the bottom left of the screen. Sonic's sprites are from Sonic The Hedgehog 2 on the Sega Mega Drive, except for his handling sprites, which are from Sonic the Hedgehog 3.
