Instructions
Turn on your Sony PSP and connect it to your computer via the USB cable. Select "USB Connection" from the PSP menu to place the device into USB mode. A window will appear, giving you access to the PSP memory stick.
Locate the game that has the corrupted data title. It will be located in the "PSP" folder, inside the "GAME150" folder. Right-click the game file and click "Cut."
Go back into the "PSP" folder and locate the "GAME" folder. Right-click the folder and click "Paste" to move the game into the proper folder. Press the "O" button on the PSP to safely disconnect the PSP from the computer after the transfer completes.
Go back into the PSP menu and you will now see that the game does not present the corrupted data title. Select it with the "X" button to play.
