The”MPH Firmware Launcher”allows to launch a firmware from the PSP’s memory stick. The firmware must be in file format and not in eboot.pbp format, for convert a firmware eboot.pbp in file, use the psardump02a tool. This patch by miemt11 is doing the following:
u2 version:1: L+R+SELECT to load the real/hardware original Sony UMDu1 Version: (FW 2.00 and 2.50)1: reduce overall eboot size by 30KB2: L+R+START to quit emulation (as requested)
