A LocoRoco demo was realeased with the 2.7 firmware and is pretty decent. But I noticed that the file that you put the eboot.pbp into looked a lot like a savegame file.

Here is the site that you download the eboot.pbp and from and there are instructions to make and name a file called "UCJS1O041".
When I first read it I thought it was 0041 instead of O041 and it didn't make the game file currupt. So then I went back and renamed the folder to LocoRoco. Still, the file isn't currupt.
So I was wondering if I could make a folder named UCJSO041 and put an eboot of a homebrew file in there and see what happens. So I put a homebrew eboot.pbp and, of course, the file is corrupted.

My questions are,
1) Why even bother with a file name that's so damn complicated while making these demos?

2) Why does changing the file name of a savegame make it corrupt, but not a demo?

3) If Sony uses some sort of signature to acknowledge a firmware update and a demo, why is it so hard to figure out how to duplicate it?

It still wouldn't work because we would still need the key which no one has bothered to look too hard for unless I'm mistaken which I probably am. I might start looking if no one has spent over a week trying to find it yet.

We will not be able to replicate the encryption used on the EBOOT without knowing Sony's encryption key. And no, you can't get that key from the EBOOT itself.

yea i think we all no that freeplay because the eboot is encrypted

Then we will just have to jump inside Sony's VIP's mind and look there. And how do we know it's not in the eboot? Isn't there a decrypter we can use on this?

It's not in the EBOOT because there's no need for it to be there. That would be a huge security breach on Sony's part.
