hi everyone... just got my very first R4 DS for slot 1 and M3 Perfect Lite for my slot 2 stuff... i've downloaded all the latest firmware and so far everything looks great! i do have one question tho... is it possible to turn on the DS, the R4 boots up... then i select "Slot 2".. the M3 boots up... but when i try to play a game, it black screens... when i take out the R4 DS (slot 1) and boot to the M3 Slot 2, the games work fine... can this be done without removing the R4 DS? also i get errors 'save data directory not found'... what is the file structure needed for the M3 to perform without those errors? thanks! i love these things, thanks for your time ppl!
