I'm using goomba gbc emulator through my ds to put on my ezflash3in1+ so I can let my friend borrow it and beat pokemon green (a game on both of our bucket lists) but it refuses to save. Do I need a gba cart with its own memory? If so is there another way to play gbc games on an ezflash? (I've already decided that he can't borrow my acekard because than I can't do anything with my ds).
