Is this thing for running homebrew & ds & gba roms on the DS?
Can anyone clear this up a little, cause I`d like to buy something
for my DS that can do all of the mentioned above.
Quiest: This allows you to run NDS ROMs on the NDS, but this just bypasses the protection. You also need a flash card that goes in the GBA slot. something like an M3 Perfect CF/SD or SuperCard CF/SD. These are the most common since they use standard SD media You an also get other flash cards and such that will work with a PASSME device.
The other advantage of this is that GBA ROMs can also be played (don't need the PASSKEY for that either)
Summary:
PASSKEY + M3 etc -> play NDS stuff
M3 etc -> play GBA stuff.
