I'm sure this issue has come up countless times, but after an hour or so of searching here, other forums, and even Google, I got nothing. I'm using an R4 and EZ-Flash 3in1 combo with Rudolph's Expansion Tool (or whatever the predecessor to his GBA eXploader is called). I've patched all my roms that needed to be patched, I have both the GBA and SAVE folder (and save files do appear in the SAVE folder), and I've tried both PSRAM and NOR for everything (I only have 4 roms anyway). I load up the Expansion Tool, and try to run in PSRAM. - "SRAM save data not found - Can't backup to SAV file" - and as expected, the rom loads, the game saves fine (no in-game error messages like corrupt data), but next time I go to play, it won't load it up. NOR mode - Same message. However, the game WILL copy to NOR and let me run it as if the 3in1 was a regular GBA cart, but it just won't save. Also, when I tried the GBA Exploader, I got a message saying to set the Slot-2 device to the program or something along those lines every time I started the loader. My guess is the battery is dead or something. In this case, is there any way to recharge the battery? Or should I just buy a new 3in1?
