Can GameBoy Advance (VGBA) save states be transferred to other emulators or hardware?
There are two kinds of saves in VGBA (on which the MorphGear GBA module is based): • State saves (.STA files). These are native to VGBA and may even change between different VGBA versions. You can’t transfer them to other emulators. • SRAM/EEPROM saves (.SAV files). These are basically copies of whatever has been written into cartridge SRAM, FlashROM, or serial EEPROM. You can easily transfer them to the real GBA (with a flash cartridge that has memory for them) or to other emulators. I suppose you may need some conversion program for that, but as far as VGBA is concerned, these are just saved as plain data files, no headers, encryption, or anything else.
