Hey guys! I followed all the directions. I am using a 1 gig MicroSD card (Kingston) and used the most updated software. I AM ONLY using the M3 Lite for GBA, not for DS games. Anyway, I left the options as default in the newest m3 game software, and wrote the games to my microSD card. All the games show up and PLAY fine, but none of them save. I have .DAT files for each and every game. Every time I start one of the Super Mario Advance games I get a warning about how my save is corrupt, for example. I am assuming I am doing something wrong. If someone could help I'd appreciate it much!
