oh and whats the difference betwen the

supercard lite and the supercard lite rumble?

well i guess passkeys don't really matter, its just for firmware version

im guessing the passkey 3 can be used on later ds'es like the ds lite

i dunno you pick but the rumble doesn't really ring a bell but don't worry about it i don't think it has any consequence of when you use it.
