I recently have been attempting to playing a variety of GBA games on my M3 Lite flash cartridge in my DS. I am able to play DS games perfectly fine, so I am a bit stumped as to why the GBA games aren't working. Instead of running the GBA rom as presumed, it instead shows a blank white rectangle in place where the game normally would appear - there is no audio, as well. I have tried switching the GBA screen preference from top to bottom - both result in the white screen. I have also attempted various filesystems on my 1 GB MicroSD card (FAT32 - M3 software doesn't boot, FAT16 - works fine [tried default blocksize, 16k blocksize, 32k blocksize and 64k blocksize all with the same result]). I have tried booting the GBA roms with the A button (for "Fast Open"), which results in the loading screen sitting at 000000 KB, and Start button (for "Open"), which does load the GBA rom, but results in a white screen. In a nutshell, no GBA games have worked so far, so I am quite stumped as to what is wrong. Thanks for any help that can be provided! EDIT: I am using a M3 Lite, which I believe has support for 32MB GBA ROMs, so I believe that isn't the issue.
