Homebrew developer roe-ur-boat dropped by QJ.NET PSP Development Forum and released version 1.1 of the application F0 Spacer. In a nutshell, this program is designed to backup your PSP's flash0 as well as dummy unimportant files in flash0 to create up to 2.5 MB more space.

Take note that even though just one developer made the release, F0 Spacer belongs to a group of coders collectively known as Team aXr^2. Anyway, the following have changed since the first build which we believe was not publicly released:

• v1
• First Release.
• Bugs: Will not backup if you don't create "fpbu" folder in ms0:/.
• v1.1
• Added "about" Section.
• Now the program goes back to the main menu instead of exiting after using a function.
• Flashing Speeds now faster!
• Fixed minor bugs.
• Fixed bug mentioned above (see v1).
