krHACKen, is to create a collection (such as games)?

Re: SCEE Demo Disc Menu
 

volgame, it is a menu extracted from a demo disc. With this menu, you can create a compilation of games, like collector discs.
Basically, it is an ELF launcher, like "PS2 Multiloader", but more compatible. The CONFIG.TXT can be edited to add your own ELFs on the menu.

The example BIN/CUE is just a test, for demonstrating how it does work.

This tool is awesome! In that way, you can even make your own demo disc with your own demos included!!! I wish there is also a way to make a demo disc menu for the PS1, which would be also cool, if I could make a PS1 compilation using these menus.

Re: SCEE Demo Disc Menu
 

PSone "Future Demo Discs" have their configuration hardcoded in the EXE :( . I'll check later if there is a menu that can be customised...
A homebrew solution exists, "Demo Menu" coded by Loser. That's the menu used in Pavlik's Hacker Kit.

For now I continue hacking the other SCEE Demo Disc Menu versions... Differences between versions are mostly GFX changes, and some features like "NOINTROMOVIE" and "HIDDEN_OPTION" being removed.

I just understood how "HIDDEN_OPTION" works. Items definied by "HIDDEN_OPTION" are not displayed on the menu until you press L1+L2+R1+R2 to unlock them.

The project goes on... I've hacked a bunch of other versions.

No release/upload for now, because I should receive a pack of demos in a few days, and will have to identify their menu.

Crypto stuff of earlier demos (2000-2003, with CONFIG.DD2, FRAMES.IPU, GRAPHICS.DDP) is stronger. Future "accidentaly" leaked a crypter/decrypter for the config file. It's called Demo Disc Config Tool. So, decrypting and building a CONFIG.DD2 is not difficult, but hacking the ELF is.

I counted 15 different versions of the SCEE Demo Disc Menu (based on their original CRC32), including earlier versions. Generally, differences are minor graphic changes, module updates or option implementations (like the very useful "NOINTROMOVIE").

Re: SCEE Demo Disc Menu
 

I have built myself my own demo disc with my own games, but here's a problem: After a demo of a game ended, it goes back to the PS2 Browser menu in the BIOs and not back into the main menu.

And when I also rip out the SCEE_DD and the SCE_DD folders and an SCED file from a normal 2004 demo disc and then put it into my demo disc and also replace the Config.TXT with the one I made myself, the disc simply won't load up for some strange reason. I think I need to encrypt the Config.TXT, so I would be able to make my own demo disc run. Is there any way to do it?

Re: SCEE Demo Disc Menu
 

I think you have to edit the ELF of your demo with an Hexadecimal Editor, to correct the path of the menu.
Most demos try to execute SCEE_DD\SCEE_DD.ELF when the demo ended. Sometime it's SCE_DD\SCE_DD.ELF. Replace this with the correct location of the menu ELF, for example \1F668570.ELF.


CONFIG.TXT files of original demo discs are crypted. There are 2 ways to make your own disc with files from an original demo disc. Encrypt your CONFIG.TXT files or hack the ELF so it can "understand" a plain text config file.

CONFIG.TXT ENCRYPTION/DECRYPTION (2003+ DEMOS ONLY) :
The algo is quite simple. It's a byte-per-byte XOR. The XOR key is :
[ASCII]
[HEX]
The CONFIG.TXT can be easily crypted/decrypted with an app like CrypTool, or you can code your own little program.


HACKING THE ELF (SCED_###.##/SCE_DD.ELF/SCEE_DD.ELF) :
The fastest way to disable the crypto shit of the menu is to open the ELF in an hex editor, search for :
and overwrite it with 00.
Then you can use a decrypted CONFIG.TXT file with it.

Re: SCEE Demo Disc Menu
 

I've coded a quick and dirty DOS apps for your CONFIG.TXT encryption/decryption needs :
DEMODISC.ZIP

Just drag and drop a CONFIG.TXT file to DEMODISC.BAT, or use the terminal.
