hi all, i have 2 4gb pro duo card. both of them r fake but 1 is normal 4 gb while the other is high speed 4gb. the normal 4gb memory card works fine but the high speed 4gb got some problems. it can store most of my games as it should be but when i slot in the card into my psp, the psp can onli read the games inside the psp but couldnt play the game. do any1 have any solution to this problem? pls give solutions that allow me to fix the problems and not alternatives like buy another 4gb psp card. and if u need to know, i got the card from a from who bought it from china. i dun think that the card is spoilt since the psp still can read it, so pls help if u know how to solve this problem of mine, thx.
