I've got the latest PPRE, editor.exe (Kiwi.ds), and BTX Editor. I've started to change the overworlds in a HeartGold ROM and everything's been working fine (Walking, running & bicycle). What I'm inquiring about is how to do the following. - Edit mugshots. - Edit trainer sprites. - Edit trainer's Pokemon. - Edit the protagonist's back sprite. And does anyone know the addresses for all of the protagonist's overworlds? I know the following: Walking & Running: 69 Bicycle: 171 Surfing: 173 Any help with this would be appreciated. Thanks, Greg.
