Surprise, surprise, surprise! A new custom firmware has been released by homebrew coder U3-Robot. Custom Firmware 5.50 U3R is based on the recently released 5.50GEN by GENyUS with some additional features like a shutdown option for VSH menu and speed up option for recovery menu. And just recently, a bug fix update was released to fix some issues.

CFW 5.50 U3R changes from 5.50 GEN:

• VSH Menu has SHUTDOWN DEVICE option.
• Recovery Menu has SPEEDUP MS options.
• PSX games may work, but I'm not 100% sure (this means NOT TESTED).

Installation procedure:

• You must install first 5.50 GEN as a shell (framework).
• Copy u3rloader folder from a zip file to /PSP/GAME
• Start 5.50U3R Installer from Game - Memory stick.
• Click X to install firmware.
• Enjoy!

And here is the changelog for 5.50 U3R-2:

• Fixed PSX Games - they are now working. (tested on Gran Turismo)
• Fixed exit with O button - now working.
• Added built-in plugins: (only for psp-2000, and still under construction)
• LEDControl 0.2 (not working on my 2000)
• Hold+ 3.7 (working on my 2000)
• MusicPRX 390 (not working on my 2000)

Installation procedure:

• You must install first 5.50 GEN or 5.50 U3R as a shell (framework).
• Delete u3rloader folder from /PSP/GAME if it is.
• Copy u3rloader folder from a zip file to /PSP/GAME
• Start 5.50U3R Installer from Game - Memory stick.
• Click X to install firmware or Up with plugins.
• Enjoy!

As always, please be careful in installing any app that deals with your flash, if you do not know what you are doing there is a chance of bricking your PSP.
