help me please

im getting a psp used from ebgames and is there any way you can find out the firmware before you buy it. because i would really like to play monkey island when im on the road or going some where and there is no way i can get that GTA game to make it work cause not aloud to play it.

were can you get the m3 or supercard for less then 100$ that has the passcard 3 or whatever the thing is called

if you get the m3, supercard or gba movie player do you need to flash your ds because i dont want to do that. and with the gba movie player do you still get the touch screen to use for scummvm

can some one help me i want to play scummvm on my ds and what do you need to run them and is supercard better or is M3 adapter and i have the original ds.
