So youre all custom firmwared out, now what? Now its time to extend, taking your CFW to the next level with Custom Firmware Extender (CFE).
Originally put together by Cpasjuste CFE is a collection of plugins that enable a number of things: jam your own tunes in game, play ISOs/homebrew over USB, change the CPU speed, better brightness control, control each individual audio channel and the list goes on.

This updated version of CFE, according to the source, has been tested on 6.35, 6.38 ME, and 6.20 PRO-B4. Depending on your PSP model some features *may* not be available.

And you can thank ?whatever? for updating CFE. Cheers!

Thanks!
