Well, I finally got the later Golden Tee games to work. Mainly the Tournament versions of the games, including the 2K versions.
Here's how I did it:
After pressing F2 (admin MAME button) in the game and disabling the "ITS" and "Modem" features in the "Tournament" menu, I tried exiting with the player 1 button and it would keep on staying with the menu. Exiting the menu (even though it doesn't exit) is key because it saves the settings of the disabled stuff that you just did.
Then I pressed F3 to restart the game. It keeps going back to the menu. I did this several times (pressing F3) and even held it down and nothing, it kept going back to the menu. So I exited the game completely and then executed the game again. Voila! Success!
Hope this helps!
