please help me im a noob at ds stuff and i have been using the search button but there isnt as much stuff listed for ds's as psps
The Supercard SD sticks out more than the M3 miniSD, if it is an old DS (not Lite) the newer M3 mini SD does not stick out at all.
The Slim SD is a remodeled version of the normal SD. It is basically just smaller. Size list of M3's Largest CF SD Slim SD Mini SD Mini SD v2 Smallest
see if i only wanted to run roms backup copys of ds and gba games would the supercard be ok as i only really have roughly 60 quid for all the homebrew stuff about 110 dollars
The passcard3 is the newest, it is plug and play, so no hassel loading games with it, get a EZIV if you don't need homebrew, avoid the supercard if you want to play GBA games.
