2. Installed files
At next, we take a look to the installed files.
The MSI95.DLL is the Matrox Simple Interface library.
The DD2.exe (Win) from the Retail PC version is from 12.Nov 1996.
The DD2.exe from the Matrox version 11.Oct 1996.
The SCUS_943.50 from the PS1 Version 26.Sept 1996.
The MAIN.EXE from the PS1 Rolling Demo 14.July 1996.
And now to the DIRINFO file, which has no file extension. This file contains all gamefiles like textures, soundfiles (exept music)...etc.
Retail PC 31.Oct 1996 - 21,1MB
Matrox 2.Oct 1996 - 18,8MB
PS1 26.Sept 1996 - 15,5MB
PS1 Rolling Demo 14.July 1996 7,3MB
We can see that the Matrox version has more files.
So, we can think that the Matrox version, is an older version of the Retail PC version... Because the files from the Matrox version are ~ a month older. No, after i extracted the files from the "DIRINFO" file, we will see, that the Matrox version is a port of the PS1 version. Because it uses the same file extentions. In the Matrox Mystique package, was a letter included, which says that Destruction Derby 2 is not yet released. And you have to fill out a coupon to get it.
I think in late 1996 you have got the disc with the Monster Trucks Demo. And if you bought the Mystique at 1997, you got the disc without the Demo, or seperated. The Retail PC and the Matrox version, shares the same "README.TXT" files, with one exeption. The Matrox version has at the end (credits), companies like Sony, Goodyear, Mad Catz and others.
