Is it a good idea to format your sd card once in a while? For the first time, Multiple GBA game Save files corrupted at the same time. which sucks. It may have been a final fantasy 6 advanced game I loaded recently, I saved, and opened the save and was stuck in some weird ass position, i dunno just speculation. all the saves on my nds games are in tact. God I hate these freakin GBA save games on the m3, nothing but trouble on the m3.
