Oh, okay. I understand. Yeah, I wouldn't know about playing any DS games on my PSP.
1: I don't own one. :'(
2: I wouldn't know how to do it if I did. D':
By the way, I don't know if you already knew this, but there's a different between a complete rom hack and rom modification.
A complete rom hack is when the game storyline is changed completely. Events, scripting...Stuff like that. My favorite one are Flora Sky and there another one, but I forget it's name. It has Fakemon and new music in it. And it's not Topaz. LOL
A rom modification is when the game storyline is completely the same, the only thing different, it's harder and every Pokemon is available and stuff. There's stats and moveset been changed.
A complete hacks takes more time to do then a mod...I probably will try my hands at a 3rd gen one of these dayz...Maybe...I wouldn't count it tho. LOL
