Is there any way to extract a saved game from a GBA game without Action Replay? Mine is long dead, and I only have DUO now.
We may have a problem. All of us are assuming you have some sort of homebrew equipment, when you didn't state whether you did or not. Do you have a Supercard or M3 or R4 or anything like that? Heck, for that matter, do you have a DS or just a GBA?Method 3 - Use cart_save (download from this site). Requires you to hot-plug between 3-in-1 type device and actual gba cart. Again, I didn't get a working save file from this.
That's because the 3in1 is not DLDI-compatible as it has no filesystem.
How would I use any of these programs? And how would I restore a save?
