I was just wondering why are my GBA saves getting deleted? This is the second time it happened. The first time I was unsure of the problem, but I think I have an idea now. I don't remember what I did the first time, but this time I took out the M3 Real GBA Expansion pack out of SLOT-2 over night because I found that it drains out the battery. Could this be the cause? Maybe the internal battery for the RAM dried out?
