I installed the Oldtimer Ballparks but they do not display on my game.

The oldtimer ballparks require a number assignment to the team that will be using that ballpark graphic. Click on or highlight the team in question, go to the Team menu and select Update Ballpark Info. The second field on the screen will be the ballpark Code #. Type the ballpark’s respective code number here.

Note: ballpark code lists can be found under the Help menu. Click the Index button and search the alphabetical index for “Ballpark Codes.”
