InnerFire Project has released a new corrupt data remover for the PSP, a PC application which removes corrupt data icons on 1.5 firmware PSPs, that are generated when using kXploit. Although there are a few other corrupt icon removers already out there, the more options there are, the more compatibility, so good work guys! The application requires .NET Framework v2, so make sure to download that before running.
