well its not a battery issue. im just looking for a reason as to why i cant save. this is exactly what i do when i start.
>boot up gba exploader, "may i set this slot2 expansion pack for gba exploader?" comes up, i run
>go to advance wars rom in PSRAM mode, current SRAM save says "empty or new state", I press A to run
>save after 1 mission, turn off and reboot
>step 1 and 2 again
>current SRAM state still says "empty or new state", no saved data from last time, first mission acts like its never been completed
