Got pics of example gba bootlegs with no save hardware?
IIRC someone posted here semi-recently about a GBA Minish Cap bootleg that had the save embedded in the ROM, though that one wouldn't save. It came with a save already on it and any time you rebooted it was reset back to the original condition. Reminded me a bit of some creepypasta

Anyway, from dumping the ROM he found out that the save was actually embedded in the ROM. Guess they forgot to use a rewritable flash chip or something?
Both the rom and the save will be different from a standard rom and save good luck trying to get it to work with anything else.
I've never even been successful restoring the save to the same cart it was backed up from always corrupts no matter what method used.
That's probably because it's using a different save type, it should be possible to convert the save though. If a tool doesn't exist for it, load the bootleg ROM in an emulator, make a save state, load the save state in the unmodded ROM then save. Should work if they didn't make so many changes to the ROM that the save state is incompatible.
That is what I said. ROM file = .gba
Dumping the ROM won't normally dump the save unless the save is actually embedded in the ROM (which I believe is still rare)
