Jojodu0010 and Marc6310 have just announced the release of a new application, titled Ico Applicator. This app will allow users to change the icon their PSP’s memory stick displays when it’s hooked up to a PC, and carries 60 different icons to choose from.
Pressing the directional keys or the analog moves the onscreen cursor, pressing “X” selects an icon, pressing L/R moves between the selection pages, while “Start” will exit the app.
To get Ico Applicator working:
UnRAR the file, and unload its contents into the GAME/GAME150 folder.
Run the application
Choose an icon
Exit the app
Connect your PSP to a PC via USB mode
If you followed the instructions correctly, the icon you picked out should display in place of the generic disk icon.
