Hi, downloaded and ran the 2 card swap trick the other day, and played about with some homebrew etc. However played Tiger Woods on UMD today, went to save and it would not let me, said there was a problem writing to Memory Stick, pulled out cleaned contacts etc tried again same prob. When I go to home, is recognising MS and will read from it but will not let me format/write to it. In my PC reads/writes fine, formatted MS and tried again, same thing. Tried a second MS again MS is fine in Phone and PC but will NOT write to on PSP, even in USB mode, just reads, wont write. Any ideas? All help would be most appreciated.
