At this point in time I have a 2.81 PSP (Was once a 1.5 but I was stupid at the time and did a upgrade) and I saw that you can go to 3.03 and downgrade with GTA:LCS that has the PSP Update ver 2.00 updater below the UMD button in the Game menu. I do not have GTA:LCS but I do have Armored Core Formula Front: Extreme Battle that has a 2.00 version update button. So my question is can I use this in the place of GTA in the downgrade process?
