right, well an answer to ur initial question, if u bought an older passkey device like ezpass2 you would need to own an original game and program the ezpass2 to work with the game you own. if you buy a 3rd generation plug and play passkey device like the super key or passcard3 (super key is the only one to work with ez4/lite if thats what you own) then u do not need to own an original game and can just put the passkey device in the ds slot, the flash cart with flashme on it in the gba slot and then proceed to flash the ds.
