I've followed your isntructions, and inserted the sprite, but when i write to ROM (the first time) two things happen:
1)i dont get the "ptr found at XXXXXXX. changed" message.
2) if i press previous and then enxt the sprite will have become messed
Also, i've noticed my unLZ is different to yours. it doesen't actually have room on the image offset for two 00's, the set out is different and it doesen't give me the "auto abort if new data is bigger" message. I was wondering if you:
a) know what was wrong with what i'm doing
b)could tell me what version of unLZ your using, to check if mines outdated.
other than that, its a great tutorial. i like the way used screen shots. helped alot.
