Hi, My gf has been playing golden sun 2 on her GBA SP. We've had the original cart around a year now, but it wasn't played until about 3 weeks ago. She's played on and off the the last couple of weeks, and been making good progress. Then she took a little break from playing (10 days, tops). She fired it up last night to play, and her save's disappeared. We've tried the obvious things like removing/reinserting the card but no joy. I'm aware that flash carts have save batteries that can run down, and need regular use to work properly. Does the same go for game carts too? Is there any way we can retrieve the save?
