My friend is a fan of the "moemon" rom hacks, namely the emerald version one, and since I used to hack pokémon roms as a kid I said I'd have a look. Moemon is just the regular game with some sprite changes (and one text change which I have already fixed). The problem is, it's missing a few pokémon, such as Gardevoir, Voltorb, etc. I have managed to get my hands on a copy of the Japanese IPS patch and patched a Japanese rom, as I know they're complete.
What method can I extract a sprite from a Japanese emerald rom (front and back)? I used advanced sprite editor on another one but that only has ini files for english roms. Also, is there anything special I need to do since the emerald sprites are animated?
