Hi everybody,

Some months back I was ripping my PS2 discs so I could rip dummy files etc to shrink the size of the iso images and store them all into one portable HDD so I can play them when I travel.

While I was investigating/browsing the contents of Digimon Data Squad, I found that there is a really weird file on the disc. The filename is "DMY1G.001" and it's roughly about 1,05GB. I gave a look to it and it looks like somekind of archive or iso image of a disc! The game doesn't seem to call any data from it so it's somekind of a filler/dummy file. Now trying to extract the contents of this file using a generic extractor seems to kinda work (it even extracts a file called "DMY1G.002") but it's not quite right, I can't explain why or what's wrong but you should better see it yourselfs.

The contents of "DMY1G.001" seems to be somekind of an iso image of a PS2 game, no idea which though, you can check the ELF file for details. Since not all files extract (or extract correctly?) compiling the files into an iso and playing it on PCSX2 doesn't seem to work. The supposed disc also comes with a code "SLPS-12345" which looks like somekind of a rough disc, for sure something that is not a release candidate.

I would like advanced data miners to give a look at it, I may be possibly missing something and this archive could possibly extract correctly after somekind of modification or something.

wtf

The file contains data from Legaia 2: Duel Saga. In fact, the Japanese release of Legaia 2 contains the same DMY1G.001 file. It's identical byte for byte.

But the odd part is that Legaia 2 was made by Prokion, this was made by Namco. Obviously meant for dummy data, but still. It looks like that the files inside DMY1G.002 are from an even earlier version of the game. The Japanese final was compiled 10/31/2001, the version inside the first DMY1G.002 is from 7/7/2001, and the version inside of the second DMY1G.002 is from 3/6/2001. The version inside of the corrupt DMY1G.002 is from 2000. Wow.

There definitely is some data that can be extracted, but it's pretty strange. As you said, the extractable elf file can be viewed and it's twice the size as the retail executable for Legaia 2.

I guess whoever was working on this game also worked on Legaia 2.

WOW, I guess I'm always after something REALLY strange.

We should try replacing files, with the retail version.

I doubt that the file is corrupted though, I think that we simply extract it in the incorrect way.

The alt attribute should be used to give a short description
of an image; longer descriptions should be given with the
longdesc attribute which takes a URL linked to the description.
These measures are needed for people using non-graphical browsers.

For further advice on how to make your pages accessible
see http://www.w3.org/WAI/GL.
You are recommended to use CSS to specify the font and
properties such as its size and color. This will reduce
the size of HTML files and make them easier to maintain
compared with using <FONT> elements.

You are recommended to use CSS to control line wrapping.
Use "white-space: nowrap" to inhibit wrapping in place
of inserting <NOBR>...</NOBR> into the markup.
