I'm trying to launch Theme Park via Heroic Launcher on Steam Deck. Whenever I launch it the game attempts to launch, screen goes black and then closes. No error message or anything.
I have other GOG games running via Heroic Launcher but Theme Park is the only one I can't get to launch properly. Any help would be appreciated. Thanks for reading :)

It's a Dosbox game, just slam it into Staging and be off on your way.
