So it turns out that doesn't seem to work. I'm using 1.5b3....I enable "GBA Support Beta," and made the 2 directories. I'm trying to use Zelda, and super mario advance 2, and when i save in those games and then power off, the progress is lost next time. Also, i should note, that I see a zelda save file in GBA_SAVES, but I guess it isn't working?
Anything else, or stuff I may be forgetting?
