With a hex editor search in file CM5000.EXE for the byte pattern (in hex):
83 bd 88 fe ff ff 02
and change the "02" to something different (if you change it to 01,
Chessmaster won't work under Windows 95 anymore).
That's it.
The offset should be:
0xcf11 for version 1.0.0
0xd3a5 for version 1.0.2

Here are a few notes:
- You have to install Chessmaster 5000 under Windows 95 first. This is
easiest if you have a dual boot machine WIN 95/WIN NT 4.
- Sometimes the title screen hangs eating up all the CPU. Simply remove
  or rename title.exe in your CM5000 directory.
- You may have to install the CM5000.TTF font manually under NT.
- Radio buttons and check boxes won't display.


Here is what Hans said about this:
"What a saga!
With a degree of experience here is where I have been:
1. yes, cm5k will run under NT4.0 BUT, here are the 'minor' points
a) you must do the binary patch. I found that the patch had to be applied
to the Cm5k.exe AFTER the 1.02 patch available from chessmaster had been
applied.
b) this installation must occur under win 95. I have attempted to drag the
files off the CD-rom and use a     patched cm5k.exe. I ran into problems
with various dlls that i was unable to resolve. I worked around this by
installing cm5k onto a collegues machine (which ran w95) then I dragged the
installation from his machine to mine
(across a lan). It ran! - so long as I did not do a right-mouse click on a
blank part of the screen (for instance to bring up the window context menu)
and a few other issues such as random hangs and addressing exceptions.
c) once cm5k was running, I found that check boxes did not appear and that
i had no cursor when i moved the mouse over where I knew the (invisible)
check boxes to be. This could be a display driver issue(?)
d) ODBC kept breaking (again!) It is getting hard not to verge on the
slanderous side of commentary in regard to ODBC (it tends to break in the
real world too). The problem under winNT was that the easy fix - reinstall
- just became a degree harder - see point b)

I did not do this on a flaky platform either - I was using a toshiba
tecra500, Windows NT4 at service pack 3 and also the toshiba supplied
display &etc drivers from the toshiba web site. All I can say is, that I
finally got it all working - after a fashion (man triumphs over machine
again!) but the battle was not worth fighting.
