Hey, so I have an M3 adapter, and I'm still pretty new at all this. I don't know what exactly the model is, since my friend gave me this as a gift. Here's a pic though if that helps. Right, so when I first got this like a year ago I put old NDS/GBA roms on it, using the M3 wiki to patch nds roms correctly. However gba ones worked fine every time without problems, using the M3 Game Manager software. So I got a new sd recently and decided to load a bunch of gba roms and when I try to play them on the ds, the file loads to 00000kb and doesn't load past that. if I run it in ds mode, with the passkey, it loads to a black screen. same rom, same settings, no clue. of course I could be doing something dumb. thanks in advance, new to the forum and it looks awesome!
