I've been searching for months now for a way to back up my GBA and GBC gamesaves so that I can use them in an emulator. Almost all of the solutions I've seen seem to be out of production. I specifically want to backup Pokemon Yellow and Crystal, because I have hours of play time on them and would hate for the battery to run out and lose the data. Could you guys please suggest how I can do this? I'm looking for a device under $50.
