I'm trying to load games off of my computer to play on my psp because my memory stick is only 1 GB but games like Little Big Planet and GTA Chinatown Wars result in a "Error Loading Application 80020418" error. Older games like Ratchet and Clank: Size Matters and Secret Agent Clank work just fine. iRShell shows "5.00" on the top right but I can't update it to 5.50 because it says update not needed.
