[melenor]

i have been looking on the internet for the best .nds, and .gba player for the NDS lite and this is what i have found, if anyone knows of any better one plz tell me and put a link, but about the M3 Perfect, what is the difference bewteen the Passcard, and the passkey, and which one would work if i want to play NDS, and GBA ROMs.
i have also heard good things about the NDS max media launcher, but what Flash kart can i buy for the DS lite, not sticking out from it, that would work with the launcher, (i would perfer to find a Flash kart that uses an SD or Mini SD card)
i have not found any of these expect for the DS Max
Media Dock but are there any like it that use SD cards and that work with GBA and NDS ROMs?
i have found EZ here http://www.gamersection.ca/index.php?cPath=30_33
