I would like to play this series using my Steam controller, but I'm having trouble.

Even after I add the launch arguments from the GOG shortcut to Steam as a non-Steam game and customize controller bindings from the Steam menu, the Lands of Lore doesn't pickup my custom Steam controller setup and just uses my default desktop bindings.

Anyone know how to make the DOSbox instance and Lands of Lore work with the Steam controller configurator?
