I have encountered an odd problem with my M3 DS Real. Note that other then this problem, my M3 works fine and I am very happy with it. =) So anyway, it's with GBA Roms. They run fine. I have the GBA expansion in the slot, and the roms I use are fine (I think. They work on VisualBoyAdvance, anyway). But with some of the games, I encounter a problem. They run fine, they save, everything. But when I turn it off and turn it back on again... the save data is 'blank'. The SAV file still exists, but my data is gone. It happens infrequently with some games, not at all with other games, and every single time with a few others. I have gotten to the point that I am afraid to play my GBA games because I am afraid that it will delete my hard-earned saves. So. Is anyone familiar with my problem? Do you know what's wrong or how to fix it? It would be much appreciated if you could help. Thanks. EDIT: Umm... I'm not sure what happened. Duplicate thread.
