My 4 month old Ezflash 3 in 1 does not save in SRAM anymore. In GBAExploader it asks ”may I set this slot2 expansion pack for GBAExploader” every time I load it up. so, I figure that this is a classic 'battery' problem. I bought a new CR1220 and followed the guide in this site.. and guess what.. it shows same problem. I checked with my multi-meter and it shows I installed the battery correctly... and I was bored so I checked the old battery and you know what... it has same 3V voltage, too!! omg.. anyone has any idea what might go wrong? I had some contact issue from the day 1 that I received this product but can it cause this type of problem?!? HELP!
