Legendary PSP programmer MPH has released the source code for his Game Loader v1.1. MPH's game Loader today. MPH's game loader was the first homebrew application that allowed 1.5 PSPs to run Grand Theft Auto:Liberty City stories from the UMD, getting rid of the need to have 2.0+ firmware to run GTA.

The source code will allow other PSP coders to build on what MPH has done, or see how it works. Good news for anyone working on getting other games that require 2.0+ to run on 1.5.
