MPH has just updated his firmware launcher to version 1.3.7. This version includes the following additions. Using this program on a PSP with 1.0 or 1.50 Firmware, you can “emulate” a higher firmware version from your memory stick and gain access to some of the features 2.0+ Firmware has to offer, such as AVC video playback and limited browser functionality. This program will not allow you to play games that require 2.0+ to play, such as Grand Theft Auto. Here are the new additions and instructions to this interesting piece of homebrew:

New graphic interface
Install / Uninstall firmware with interface from an eboot.pbp or a flash0 folder
Copy flash1 files automatically
Language support
Corrected some bugs
Installation:
- For 1.00 firmware : copy MPHFL (in 1.00 folder) to PSP/GAME folder of your memory stick
- For 1.50 firmware : copy MPHFL and MPHFL% (in 1.50 folder) to PSP/GAME of your memory stick

Put files of flash0 (data, dic, font, kd et vsh) and flash1 (dic, registry et vsh) in ms0:/ (folder of your choice, default : ms0:/flash0 and ms0:/flash1) (see Firmware convert tutorial.txt in zip)

Run MPH Firmware Launcher.

Browser:

Don't use logfile with browser else browser will freeze (maybe because browser call sceIoCloseAll and file descriptor of Log file is close also, sceIoWrite failed and psp freeze).


Video file:

The AVC video must be stored in :

{memory stick letter}:/MP_ROOT/100ANV01/MAQxxxxx.MP4

where xxxxx is number (example MAQ00001.MP4).

The MPEG4 video must be stored in :

{memory stick letter}:/MP_ROOT/100MNV01/M4Vxxxxx.MP4

where xxxxx is number (example M4V00001.MP4).
