Sonic the Hedgehog Genesis is a GBA port of the original Sonic the Hedgehog game on the Sega Genesis. This port was released to mark the 15th anniversary of the original game, which also included the release of Sonic '06 around the same time. This port is infamous for being a terrible conversion to the GBA, which includes buggy graphics, tons of slowdown, wonky physics, and butchered music in comparison to the original game.
Tuffcracker manages to complete the game despite all the issues with this game, in record time.
