Pepsi in Sonic 1 is a ROM hack of Sonic the Hedgehog by Unlimited Trees (a.k.a HorriblePerson on Sonic Retro). It is a parody hack of a lot of ROM hacks out there, which is why there are things such as horrible level "designs", generic palettes, and the usual character switch. This ROM hack features 6 full length zones (plus bonus stages), 3 (+1) playable characters, and many art edits and secrets!
