There's a new single card solution for DS roms now. Before you had to use the passme2 and a card reader but now you just need the M3 DS Simply and it'll let you run a rumble pack in the GBA slot. This is great news because in the DS Lite the classic M3 Player sticks out too far and the PassMe2 is prone to freezing if the card is bumped if you leave it in. I expect to order this one in march.
