Help to replace desktop with a laptop to run ChessMaster

[Martin Hudon]

Chessmaster 9000 will not install on a windows 10 64 bit system, but I was able to install it on windows 10 32 bit in VirtualBox without problems. You can even copy the program files and document folders of Chessmaster 9000, in the 32 bit system to the 64 bit system, and run Chessmaster 9000 in Windows 10 64 bit this way.
To run it without problems you have to open Program Complibity Troubleshooter and check the box 'The program requires additional permissions'. I also enabled DirectPlay, and installed the latest patch 1.02a for Chessmaster 9000.

Yes, precisely what he said. I'm running CM9000 on my brand new Win 10 64 machine (by copying the files from an old machine) with only a few weird graphical issues due to the changes in how Windows has handled custom interface components since 2004. But it is all completely functional.

I'm also going to finally, after more than 15 years, mention a backdoor that I put in for people who may be still annoyed by the copy protection of requiring the CD every once in a while. These directions are for Windows 10, so some of the key may be slightly different for older versions of Windows.

In regedit:
Computer\HKEY_USERS\S-1-5-21-76881183-1595192616-1402393664-1001\Software\Ubi Soft\Chessmaster 9000

Create a REG_DWORD key called "RelCD" and give it the value x403 (decimal 1027)

That should bypass the CD requirement.

Thank You for your comments. Martin.

Chessmaster 9000 haze a limitation of 40 moves depth for making obk books. Douse someone know if it can be extended some way. To 60 moves or 120 plies for example. It is possible not possible but I want to ask anyway.

Well, looking at the code it appears that MAX_BOOK_DEPTH is set to 60. But there may have been a bug somewhere that limits it to 40 plies.
