How to Fix Corrupted PSP Game Filesby Joshua BaileyUpdated September 22, 2017
The Sony PlayStation Portable has a large library of games. Like many other video game consoles, the PSP has a large homebrew community that makes its own games. Everyday users and independent software developers create homebrew games. They do not have Sony code on them, so you need to be running custom firmware in order for them to run properly. Custom firmware, like homebrew, is created by users and not Sony. It is like Windows for a computer. Sometimes, however, you may experience a "Data Corrupted" error when trying to start a game. This is very easy to fix, and you will be running your favorite games again in no time.
Turn on your Sony PSP and wait for it to boot into the PSP menu, often called the PSP XMB. Connect the PSP to your computer with a USB cable and a window will appear on your computer, giving you access to your PSP memory stick.
Locate the game that you have previously placed onto your Sony PSP memory stick. It will either be in the "GAME" folder, "GAME150" folder or the "GAME5XX" folder.
Move the game into another game folder. The corrupted data error occurs when the game you are trying to load is placed into the wrong folder. If your game is in the GAME folder, place it into the GAME150 folder and disconnect the PSP from the computer.
Go into your PSP XMB and run the game. It will now display as a playable game, and not corrupted data. If it still displays as corrupted data, connect the PSP to the computer again and move the game into the final folder. Disconnect the PSP from the computer and play your game.
