If its just DS games u want to play, and homebrew, and NOT GBA games, then get the R4DS.

Putting the roms on it, is so much simpler than the M3.

But, if u want to play GBA games, get the M3..........................u can get GBA games to play with R4DS, but, i need to learn how to do so, so i cants tell ya, but yeah, for putting DS roms on, the R4DS is the most simplest.
