Configuring 'Custom Firmware'
1. Turn off PSP, and turn it back on holding "R" to access recovery mode.
2. Here you can change some options, below is a list of the common options you might want to change:
Configuration Menu:
Skip SCE Logo (Skips the PSP Bootscreen and disables UMD Autorun, see note below)
Hide Corrupt Icons (Hides 'Corrupted Data Icons' so they don't show on the Game Menu)
Game Folder Homebrew (Changes the folder your homebrew goes into, see note below)
Use No-UMD (Run games without a UMD in the PSP, some games may not work properly)
Fake Region (Use if you have UMD movies from regions that are different to your PSP)
Free UMD Region (Removes the region code on your PSP so it can play all UMD Movies)
Registry Hacks Menu:
Button Assign (You can switch the O and X buttons for Confirm and Exit)
Activate WMA (Activate WMA playback without using wireless internet)
Activate Flash Player (Activate the Flash Player without using wireless internet)
Plugins Menu:
Here will be a list of plugin files you put on your memory stick.
Note about the "Game Folder Homebrew" option:
If this option is set to 1.50 Kernel then you need to put:
Older Firmware (1.00/1.50) homebrew in the "PSP \ GAME" folder.
Newer Firmware (2.xx/3.xx) homebrew in the "PSP \ GAME3xx" folder
If this option is set to 3.xx Kernel then you need to put:
Older Firmware (1.00/1.50) homebrew in the "PSP \ GAME150" folder.
Newer Firmware (2.xx/3.xx) homebrew in the "PSP \ GAME" folder.
Note: Replace '3.xx Kernel' and 'GAME3xx' with the custom firmware version of your PSP. example:
'3.51 Kernel' and 'GAME351' for 'Custom Firmware 3.51 M33'
'3.40 Kernel' and 'GAME340' for Custom Firmware 3.40 OE'
Note about the "Skip SCE Logo" option:
If you only want to disable the UMD autorun, you can do this from the settings menu
in the XMB by going Settings > System Settings > UMD Auto-start: Off
3. Once you have finished with changing the settings in recovery mode, choose "exit" from the main menu.
