Hey Cosby here! This is a great forum post. I was wondering if it was possiblr to put a .sav file onto the original cartridge. For example is it possible to put a .sav file of pokemon heartgold onto the nintendo sealed copy of the game. I have not been able to get a solid answer. Resources I have: Nintendo DSi Action Replay DSi Acekard 2i Pokesav 4gb micro sd card. is it possible to do that?
