PSP: Power Source & Memory Stick Question.

i don't knoe whether this question hv been ask b4, but

1) is it ok if i play my psp with external power(without inserting my batt)?? What harm could it do to my PSP system??

2) i purchased 2 ms pro duo recently, the 1st one 4gb(RM60=USD17-18 (USD1=RM3.5) ) the 2nd one 2gb(RM24=USD6-7)

the thing is that both were "Made in Japan", and when i checked the MagicGate, it says "UNKNOWN"

what does it meant by that??

and guess what, a 8gb ms cost only RM70=USD20... Really confused..

By the way I am just speculating. But I supposed you're from Malaysia?defunct32

Yup, what bout playing using AC adaptor ???

1 - Playing the PSP with the power cord is fine. If anything, you will wear out he battery less quickly.

2-I had the same "Unknown" status on one of my MS Pro Duo cards, but the card worked fine so I did not worry about it.
