thethethethe has voiced my initial opinion; that although this is fantastic work for a Diamond/Pearl ROM to be hacked, there has only been the squads of main trainers and the appearances of everyone obtainable, changed.
It's damn good work, more than anyone else has achieved on here. I can't wait for more to be able to be edited from the game though, ie scripting and map. It just seems to me like this guy is raring for more hacking tools to be made for this ROM, so BRING 'EM ON! :D
I've decided not to download this one, but wait for anything brought out once more is able to be changed in the game - can't wait either way! :P
