This is a version of PKMN Crystal with stuff that I’d like to have in it (i.e. more Ghost types). It isn’t a complete overhaul or anything close to it, these are just a couple of things that I liked to have added, so I did.

The main branch is in German, but there’s also an english branch.

Based on the 16-bit monster and move index patches from https://github.com/vulcandth/pokecrystal16 (I rebased https://github.com/pret/pokecrystal on top of that); I got the data for the German version from https://github.com/mid-kid/pokecrystal (with a lot of manual fix-up, and I definitely missed some stuff).

All gym leaders, all elite four member, and the champ have at least one ghost type. In addition, I supposed if I was already this far, I might as well help myself to a gym; so I took over Ecruteak City’s gym.
