So I have a M3 GEP for like 3 months now and recently I started playing Pokemon Ruby. RTC worked perfectly but today when I started the game I got "battery has run dry" message. I checked Emerald version and same msg appeared. Then I formatted my microSD using Panasonic SDFormatter, copied new AKAIO 1.9.0 and GBAExpLoader 0.58b0, disabled multi save and still same result. I aslo tried copying ak2_sd.dldi from the official firmware. So it seems that it is hardware's fault but why? I bought M3 GEP because of the RTC function and now after 3 months it's dead? What to do?
