Description:	This patch will downgrade Doom II version 1.7a to version 1.7, which cannot be obtained otherwise through official patches. There is a previous downgrade patch of this nature, d217a17.zip, which only works on Windows 2000 and higher. I found this annoying when the game itself is for DOS, so that's all this patch requires; DOS. It should work on real MS-DOS, DOSBox, and 32-bit x86 Windows (other versions do not have the NTVDM and lack DOS support entirely).

Description             : This patch will downgrade Doom II version 1.7a to
                          version 1.7, which cannot be obtained otherwise
                          through official patches.

There is a previous downgrade patch of this
                          nature, d217a17.zip, which only works on Windows
                          2000 and higher. I found this annoying when the
                          game itself is for DOS, so that's all this patch
                          requires; DOS. It should work on real MS-DOS,
                          DOSBox, and 32-bit x86 Windows (other versions do
                          not have the NTVDM and lack DOS support entirely).

* Instructions *

Installing this patch requires having a copy of Doom II v1.7a.  If you only
have version 1.9, you can get v1.7a by jumping through several hoops.  If
you have setup disks for 1.666, you may skip the first two steps.

1. Install a clean copy of Doom II v1.9 from your install disc.
 2. Get dm2dwngr.zip from the idgames repository (directory utils/exe_edit/)
    and downgrade down to v1.666.
 3. Get d2166617.zip from the idgames repository (directory historic/)
    and upgrade up to v1.7a.  Note that the text file for this file is
    incorrectly titled; it IS a 1.666->1.7a patch, not v1.7.
 4. Install this patch to get Doom II version 1.7.

Phew!

To install the patch, extract this .zip into your Doom II directory and
run patch.bat from the DOS prompt.  It might take several minutes to
run.
