Windows 11 & old NBA games

I tried few days ago Windows 11 on my computer.
I had to roll back, because 2K9 to 2K14 dont work anymore ,black screen or instant CTD.
I tried to reinstall directx, compatibility mode etc... in vain.

Fortunately 2k15 to 22 works.
Basketball Classics works as well.

Cant tell about old NBA Live games.

Bad news for backwards compatibility for sure. Disappointing to hear.

I recently upgraded to Win11, and have found the following:

2K titles:
2K9 won't start and gives a message about side-by-side configuration not correct. I still have the disc for 2K9 and tried with this but still no good.
2K10 however worked after it asked to install an older .NET framework.
To me this suggests that there is hope for 2k11 through 2k14 so I will test those out.

Regarding Live titles:
So far have been able to successfully reinstall and play NBA Live 2005
NBA Live 2004 however I am copping some incompatibility issues and have been unable to start the game.

I'm yet to try earlier versions of Live. I had Live 98 and 99 working on my Win10 build, so when I have time I will relocate the resources that enabled those to run on newer systems and see if it works for Win11.

I'll report back with any updates once I get time to try some more older titles.

Try this for NBA 2K9: viewtopic.php?f=119&t=116086

Hopefully we can troubleshoot some of the other classics!
