I'm looking for the best flash card for my GB micro. It should be U-Disk or using storage card cause I want to be able to use it on any OS. It should support unpatched roms and every GBA save type. It don't want to use any client software (to transfer games to the card or to patch them). Does a card like this even exists? The closest to what I ma looking for seems to be the EFA-Linker II (but it doesn't support EEPROM saves).
