Update: v2.2 is now available for download.

v2.2 Changes:

• The Time Machine reboot function should now be fixed … stupid error i made. Note that the function is only made for use with NAND firmware and 150_340 one, with the TM files provided in this archive. If you want to use it with another firmware than 150_340, you will have to edit your firmware files manually to add the cfe_vsh.prx and cfe_game.prx plugins (TM/fw/pspbtcnf.txt and TM/fw/pspbtcnf_game.txt).
• Fixed some little bugs in the music player, and found the reason why it was not working for all the people. If the psp hang while loading the music menu, you should apply the dark_alex 3.71 fatmsmod.prx patch, it should fix all the problem’s.

v2.1 Changes:

• Added music playback based on music.prx by joek2100. (only tested under 3.90fw), default combo button for the music menu is NOTE+SQUARE.
• Changed the way we reboot from one firmware to another firmware with Time Machine, the original configuration file is now backup and restored at each boot.

It’s been awhile since we’ve seen an update in Custom Firmware Extender, but Cpasjuste’s back with version 2.0.

For those who haven’t seen this yet, “‘Custom Firmware Extender’ is a set of plugins that will add some extra option to your SONY PSP.” Check out the readme for a full list of features that won’t disappoint.

Changes:

• Removed usb/wifi ISO streaming for multiples reason, principaly it was not the goal of cfe at the beginning. There is now “USB ISO Loader” by psp.padawan that will do the job well. You should soon be able to grab it from http://www.mydedibox.fr/~psppadawan/
• 390m33-2 and 150_340TM custom firmware now supported (cfe should now work on any firmware), note that on the 150_340 time machine firmware, the ftpd server will not work, and remotejoy under ISO/HOMEBREWS won’t work too for now. All other functions should work well.
• Time Machine compatibility : You can now reboot “on the fly” from one time machine firmware to another, just edit the cfe.config file under “ms0:/seplugins/cfe/” to choose which firmware you will reboot to by pressing a combo button. Format is the same as the original time machine configuration file. Default configuration is NOTE+LEFT => reboot to 150_340 firmware, NOTE+RIGHT => normal reboot (NAND).
• Remotejoy fixed to work on both slim and phat psp, without savegame bugs, so it should now be completely usable for gaming and recording.
• Tested on 390m33-2 and 150_340TM firmware on SLIM and PHAT psp.
• And more, can’t remember all the work i have done on this
