I have an M3DS Real Perfect Bundle and up until not too long ago, they all worked just fine. Now, however, I cannot run any GBA games at all. Either it goes as far as showing the GAMEBOY splash screen and then just freezes, or it doesn't even get that far and just stalls on the Sakura loading screen. Starting NDS games works just fine, so there's nothing wrong with the M3DS. I have tried shoving some paper in with the GBA cart to see if there's a connection issue, but it doesn't really seem like that's the case - the disk check that shows on each boot detects the GBA cart memory just fine, and if I boot without the M3DS in SLOT 1, it shows the GBA as an Option pak, as it should. In fact, the GBA cart is so hard to push in just by itself, I can't really see it getting a poor connection. I mainly play NDS games anyways so it's not *that* crucial, but I am wondering if there's any homebrew available that can run error checks on the GBA Expansion memory of the M3 bundle? If anything it could at least tell me if my GBA expansion has gone bad all by itself, or if there's something else afoot.
