hie...i'm not sure whether this question should post it here. but if i'm in the wrong place. pls let me know.
I recently owned a psp slim with ver 3.71. The first few days i was enjoying the games installed in the mspd.
but after that i started to have frequent hang during the game, else the memory card is not detected. i've not made any changes to the psp. anyone experience this?

i think i'm using the non-ori memory card. Does anyone using the non-ori having this problem?
how much is the ori mspd 4g?

ahh ic...so i assume the main problem is caused by the memory card. Since frequent hang like this, i have to turn off the power and turn it on again. will i corrupt psp OS?
Thanx. i'll go try to look for the ori mspd. anyone got the link to differentiate the ori n non-ori mspd? saw it somewhere before but can't find it now.
By the way, i heard some said psp come with non-ori batt as well? how do i check that as well? thanx
