Packages Installation from Magazine Demo Disc

I've had a look at one of my demo discs I got from the Official PS Magazine UK (BCED00087) through multiMAN on 3.55 and I think there may be a way to install packages from a disc. The manager identifies it as an Install Disc.

Here is the structure of PS3_GAME:

PKGDIR
PKG00
ICONS, PICS, PARAM.SFO and INSTALL.PKG
PKG01
...
PKG11
ICON0, PIC0, PIC1, PARAM.SFO
PARAM.SFO

The SFOs I believe have to be precise and made specifically for package installation. Each PKG folder contains its own installable game, along with necessary artwork. I'm going to try and play around with it for a bit. If anybody has any useful information, please post here.

I've got one of these (March 2010 demo I think). I use it as my dummy disc for games that don't work discless :p

What you're suggesting is not going to happen. These discs are pressed as legit ones the same way games are. We can't perform that procedure.
