I'm familiar with the whole system of ROM hex editing, as I've been doing it for some time with success. However, I've recently come across quite a difficult task. I am trying to edit Pokemon LeafGreen on the GBA. I can find no way to tell what does what. I don't see anything corresponding to my guy, my Pokemon, or my items, let alone anything more advanced. So, I ask for some offsets, or better yet, a program to edit stuff on there.

I think there was a few more over on ACMLM's then there are here, but I can't seem to find 'em. Look through the archives and you might.
