Hello, I have a 4GB Memorystick for my psp and a 8GB one (both Sandisk). The 4Gig is ok, plays CSO etc.. But my 8Gig is painfully slow !! loads my game list slow and doesn't play CSO (it does but really laggy and slow) Is there anyway I can make it faster ... I tried FAT16 but FAT16 only supports up to 4GB MS :/ I really want to play my games in CSO format so I have more space left on the MS Any help is appreciated.
