Pokemon Peridot is a hack made with the help of pret’s pokecrystal disassembly project. This version takes place in an all-new region and features 8 gym ladders and the Pokemon League, along with post-game rematches and a battle subway.

This hack also includes a selection of previously unused Pokemon designs from various stages of Pokemon Gold & Silver’s development. Fan-created stats were added to these Pokemon to make up for the lack of final stats.

  • Previously unused Pokemon from different stages of Gold & Silver’s evolution
  • Two rivals
  • Gyms can also be completed out of sequence
