Aight. I'm looking for a save data editor for GBA that works with real hardware, in a similar manner to rtcread-ds. I know something like this has to be out there, but google is not showing me anything. Essentially, is it possible to put a GBA game in slot 2 of a ds, put a flashcart with a tool on it in slot 2, and save-edit a real copy of Pokemon Emerald? I know that there is a good chance no such thing exists, but can one of you diehard nerds help me out?
