Hack of Pokemon Red Version (using the Pokered disassembly).
Unova Red is a re-imagining of Generation 1, but using the Pokedex from Generation 5. This is because the Unova Pokedex was designed to stand alone without any Pokemon from additional regions, much like the original Pokedex. The plot is effectively identical to the Generation 1 games, the only major change is in the Pokemon available. There is also a challenge mode patch which provides a more difficult version of the same hack.

Hack of Pokemon Crystal Version (using the Pokecrystal disassembly).

Kalos Crystal is a sequel to my previous hack, Unova Red. This is a re-imagining of Generation 2, where the first generation of Pokemon were the Unova Pokedex, and the new second generation Pokemon are the Kalos Pokedex. This game features all Pokemon from generations 5 and 6, and like in Unova Red, all Pokemon in the Pokedex are obtainable within a single playthrough.
