I dunno if i followed it wrong, but if I try to use the sprite in game, the game glitches up.
It doesnt crash. but it turns the rest of the sprites on the map temporarily into black and white lines.
EDIT 1: No worries, I backed up my rom, so I can always have another go!
Everything else in the tutorial worked, so I probably made a mistake. :D
EDIT 2: It works with Overworld Editor. Yay. Now to get it working with advance map so I can get it working in the rom.
