Succeeded in downloading that .zip file. But I'm not currently visiting the Cubs, so AFAIK I can't test loading that park until I get that far, which will take several days. Is there a way?
I did succeed in creating a 1-game exhibition using the 1928 Cubs as the home team. But there does not seem to be a way to change the park files. When I tried to play it with whatever version of Wrigley 1928 it already had, it crashed in the same way as all previous attempts.
