EverDrive GBA / Re: Losing save files when battery runs dry
« on: Today at 01:18 AM »If you use the most recent firmware for the device all you’ll need to do is power on the gameboy with the cart inside after a save for it to write the content of SRAM to the SD card and preserve the save. If the save has been moved to the SD card it won’t be lost when the battery runs dry.
Yes, this is the answer. You wouldn't lose your save (since that's saved to the SD card) but a dry battery would make it impossible to save new progress to the SD card. So the worst that would happen is you lose a little progress if you didn't realize the battery was dead. That said, it's always a good idea to back up your saves to a computer periodically, especially if you don't plan to play for a few months.
