PSPInstaller 5 is the successor of PSPInstaller 4.12. PSPInstaller runs on both OFW and CFW and allows the users to easily install homebrew, themes and plugins. The Process is simply, browse the file database, select the file, and choose to download and install it straight away, or download it now and install it later! When the process is complete you can exit to the XMB to play the new downloaded game/application, or install the new CXMB theme.

Changes:

– Progress Bars for Download
– New Interface
– New Sounds
– Cleaner Code (More code recycling!)
– Working Update System
