Dark_Alex has just released his newest revision of his custom firmware for the PSP, Revision B of 3.03 Open Edition (OE). Seems like Dark_Alex has been more concerned about the PSP consumers than Sony is, issuing tons of new firmware updates (only updatable on 3.03 OE which was made possible by using firmware 1.50), so be sure to give him a huge thanks! With full resolution support for MP4-AVC videos (previously limited on Sony firmwares), you can now enjoy all your videos at "DVD quality" like it was meant to be. Having used PMP Player (which supported 480x270 resolution), this update adds the functionality directly into this new update.

You'll have to have 3.03 OE-A already installed onto your PSP in order to update to OE-B. Installation is easy as pie, just drag the PSP folder (found within MS_Root of the download) to your PSP's root directory and run the update eboot from your PSP's game directory like any other OE update which will only take a short duration since it is only flashing a few files onto it, not the entire firmware. Here's the newest additions to the world's greatest PSP firmware (at the moment) -

* Patched the firmware to allow decrypted mp4-AVC videos to play at 480x272 resolution.
* pic0.png was not shown in psp isos. Fixed.
* The speed functions were not dummied after setting the speed. This could cause the few games that set the cpu speed not to run at the selected speed in the recovery menu.
* Changed the structure of the program to have more free ram in game mode.
* sysmemp.prx removed, systemctrl.prx splitted into systemctrl.prx and vshctrl.prx
