Yeah, this method worked for my Pokémon Black cartridge. However, I didn't even have to solder the wire on, I just pushed it into the holes and bent it back and the Action Replay still recognized it. Thank you for this info!
How do I edit the sprites of overworld Pokémon? I would also wish to know how to edit the in-battle sprites of Pokémon. I already know how to edit overworld trainers using BTX Editor.
