I love the ultra portability of the GB Micro, something the SP just doesn't have, especially with a huge Gameboy cart sticking out the bottom. Hardly jeans-pocket-portable is it?
So can it, or has it been done?
EDIT: Well I've done a bit of research and am disappointed to find that it can't really be done, except for getting the Micro to crash into the Gameboy start screen
I suppose there's the flashcard option but the GB emulator for GBA isn't very reliable, especially when it comes to saves...
Any other ideas?
