Fakemon Fire Red

Fakemon FireRed is a ROM hack of Pokémon FireRed, which does exactly what the name implies – completely rids the game of official Pokémon and replaces the roster with a full national dex of only “Fakemon” – that is, fan-made Pokémon designs made by me. The game world and story still largely follow the original Pokémon FireRed. I've also added two new types, (Cosmic and Digital) the Fairy-type, Mega Evolution, the physical/special split, modern “quality of life”-features, newer items, a few changes and additions to the Kanto region, and much more.
