GBA Pak Backup/Restore save [enhancement]

[KRoman47]

Hi. Is there possibility of adding GBA Pak Dump/Restore save?
I see you've got Mother 3 bootleg as well, which should be 512 kb FRAM. I've tried several GBA save dump/restore apps but without any luck. I get some empty file that's the same every time (it doesn't change at all after any in-game save).
With common SRAM batteryless patched game I dump the game ROM that contains game save as well if I want to flash other game and decide to get back to previous game with previous progress which is impossible with Mother 3 cartridge.
