PSP CheatUp is an application designed to simplify the task of updating the cheat codes through the use of the PSP’s Wifi and a wireless internet connection.

Changes:

Added: Support for starPR and HackME.
Added: Detection of bluePR.
Fixed: Download errors which happened after a failed download attempt.
Fixed: If no cheat engine was active no item would be selected by default in the cheat engine select lateral menu.
Other: Increased message buffer sizes to 16KB so I can show you longer update messages and notices.
