If it has just lock this or delete it, I was just playing around with files tonight and actually got something to run (I have 1.50 though), so anyone with a 1.51 or 1.52 please test. I just used the Firmware 1.52 update PARAM.SFO and took out the DATA.PSP and DATA.PSAR. I put that in the folder UPDATE%, then in the folder UPDATE, I put the EBOOT.PSP (Really a DATA.PSP) of the program. In this test I used PSPaint. This WILL NOT update your firmware, it says 'Firmware Update' but its just the loader, it DOES NOT UPDATE. Just wanted to make that clear. Probobly been done, probobly wont work, but it was worth a mention.
