MPH 펌웨어런처(버전 체인저) 1.37이 나왔습니다.
이번 버전의 특징은 AVC동영상을 좀 더 안정적으로 돌릴 수 있고, 2.5용 브라우저도 실행시킬 수 있다고 합니다.

또한 전원을 끄지 않고, L+R 버튼으로 원래의 버전으로 돌아가는 것이 가능합니다.

MPH has just updated his firmware launcher to version 1.3.7. This version includes the following additions:

• Launch browser (firmware 2.50 only), see explanations
• More stability when play video (firmware 2.00 only)
• Corrected bug in config.c for comments in configuration file
• Now exit with L + R trigger

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 :

The browser is launched in firmware launcher 1.3.7 only with firmware 2.50 launched.

Before launch the firmware, erase or comment LogFile variable in configuration file else browser will freeze (maybe because browser call sceIoCloseAll and file descriptor of Log file is close also, sceIoWrite failed and psp freeze).

The browser shows 8008273A error when you enter a address (maybe because bad network settings ?, i don't have wifi on my pc to test it).

Use firmware 2.00 to change network settings and then copy flash1 of firmware 2.00 to flash1 of firmware 2.50 (because same error when go to network settings).
