Custom Firmware extender is a set of plugins for your PSP that enable all sorts of useful things and now Cpasjuste has announced version 1.4 with video capture support!

Quote:NEWS IN VERSION 1.4
===================

- Tested on M33 52-4 custom firmware.
- Fixed some bugs and probably added some.
- Capture folder for screenshots can now be set in the config file.
- Use the code from remotejoy by TyRaNiD @ ps2dev.org to record some in-game videos. All remotejoy functions
are still available.


MAKING A VIDEO CAPTURE
======================

- On the computer, go to the folder "_release\pc\windows\gui" then launch "start.bat"
- On the PSP, load a game or homebrew, then push the capture button combo (default is NOTE/VOL+). It seems the psp
will hang if you do this before a game save is loaded. Best is to do this when you really are in game.
- Go back to the computer, in the SDL windows push "c" on your keyboard to start capturing.
- Each frames will be saved as bmp in the capture folder. Note that you must have a lot of free space on your hdd,
and this one must work at a descent speed or you may loose some frames.
- Now you just have to encode the *.bmps using you favorite encoder (VirtualDub will do the job by loading the first bmp).
