I'm also getting the same as you, but I was on the understanding you didn't need to do it to a demo, it just runs on your internal drive after install. Sorry I've not been up long I could be wrong, and you may have other reasons.
Sorry bud, like I said I had not been up long, and did not think of that reason, and like a tool that I am, I thought because you was a new poster on here, you was new to playing games without the disks and maybe confused about playing demos or riped game disks from your drives. My bad.
About the Killzone 3 Demo problem: "This is Killzone 3 Demo EBOOT - I'm on 3.41 and when I tried to run the game (even with the param.sfo changed to 3.41) it wants to upgrade my system to 3.50 or higher...
I tried JB dongle with 3.50 spoof too... but after information about connecting PSEYE and Move controller it freezing my console (black screen)"
So it's prob a no go as far as param editing to get it to work on 3.41. The only other way mentioned and as far as I know, would be an edited eboot.bin

Ok so will this tool work for a regular (not hacked) ps3?
Also, will it work for a Fallout NV gamesave?
I have tried copying my account ID into another persons PARAM.SFO file, but when I transfer it to the ps3 it says the data is corrupted. I have my buddy's Save file but want to make it work on my ps3 - are there steps I am missing?
