| So basically you've been running ISO's on your version 1.5 PSP, then upgraded to 3.0 and found they no longer work. It's possible that it's because the security in the PSP's firmware has been upgraded so it won't allow people to use ISO's on updated consoles. So unless a hacker can find a way to get past the new security measures, you'll have to buy a few games.
But you've also said you reformated the memory stick? That's wiped all the files you had saved on that memory stick, including game saves, so they won't be there anymore. You'll need to copy them again to your GAME folder in your PSP (connect PSP to PC, put it in USB mode, click and drag the file to the GAME folder in your PSP) and see if they'll still work on your PSP. If not then it's likely because of the problem i mentioned in the paragraph above. |
