Hi there, first things first, this is a really nice project, regardless of whether people consider it "real hacking" noone can deny the fact that it's nicely put together and the finish on everything is nice, even if there are occasional rough patches (getting ambushed by a lvl 70 celebi was not nice XD)
I'm trying to make a custom pokemon ROM for my little brothers christmas present, I have edited the overworld sprites but can't find out how to edit the image for your trainers back and the battle trainer sprites for rival trainers, gym leaders etc. I have played your hack and your rival trainers, gym leaders and players back have all been edited, could you please give me a quick walkthrough of how to edit these (I have experimented with pokeTEX but can't find anything but overworld sprites on there :'( )
