Thanks for all the info.
Ya this disc was from the Official Playstation Magazine that I bought in Portugal so I see what you mean about the Title_ID.
It´s to bad there´s nothing special about the disc. since this was from the early days of the PS3, I was hoping there might have been something exploitable. or at least some info maybe to make a disc with multiple games on it.
Oh well at least people saw how the 1st demo discs were shipped.

Is still interesting to compare with the new "selectors" used in games as "god of war collection"
I think are pretty similar, but the one in this disc maybe is more "open" (less protected or more simple, whatever)... because is older

And im not sure if this demo discs from playstation magazine had another options in the selector menu (like playing a video or a sound track)... this kind of things are different between them
Also.. the selector for "ps2 collections" needs to trigger the "ps2 emulator"... so there must be some important differences

I have not taked a look at this selectors at code level... i cant help with this, but maybe is usefull for other people, who knows

The theory was to place a npdrm-self that gets launched by eboot, and circumvent the strict eboot checks and sign it with a known klicensee (InfinityWardKey for example.) But, i was told in v3.60 an extra npdrm sig (footer) was added into the series of checks they perform, and private aes key is needed to add this footer.. which we don't have.. So this won't work > 3.56, and thus is fairly useless unless you figure out the private key to add the npdrm-self-footer. I didn't confirm myself if it still worked on 3.56, i don't have hardware flasher to go to lower versions.

The footer signature is still not checked upon npdrm self files execution as of 4.21.

Because kakaroto says something that doesn't make it true. Basically he found a check in 3.55 that was not even called and assumed they used it in 3.60+.

Of course they do whitelist npdrm now so even if the footer isn't checked you cannot run your own npdrm selfs signed with keyset lower than 0x0D making the whole debate rather pointless. Aditional checks are now performed on the actual file format as well such as the segment counter flag that needs to be set to 0x01 except for the very last segment.

I am definitely out of the scene, I am just dropping a small message once in a very very long while, that's it.
