MPH, the same guy who did the 2.0 -> 1.5 downgrader comes through again with the ability to play the GTA UMD on a 1.5 firmware PSP.
This is great news for me, as I will never go past 1.5 until we can have the same level of emulator/homebrew support in the later firmware versions.
Now if he can just get Exit working, I will be set.
