1) Does this work with M3 DS Real? 2) Can it support a 2GB Micro SD? 3) What exactly is it for, like can it play DS games, GBA games, mp3's, etc. Basically, is it "an R4" for slot-2? 4) Will it work on a Gameboy Advance? 5) So if I run LMP on the DS, will it also detect the mp3's in slot-2? 6) Is this better than EZ-flash 3 in 1? 7) Which menu would boot up if I have it and the M3 Real in both slots?
