Hello all! Want to help a noob out? Today is your lucky day! Wooop wooop!!! I have an r4III Upgrade (Clone: Site www.r4sl.net Its running v3.12, I think that is the original OS. Well, I would like to put the best OS on it to be able to play the newest roms. (Golden Sun to be specific). I think I have all the needed info above, I am also on a mac. So opening and editing .exe files is a no go. I have tried google for hours, read a bizzilion tut's installed anything I thought would work and got various black, loading screen hangs etc. This is my last hope. Anyone want to take a poor soul under their wing and give me a hand? Any help?
