You will need to locate the game files within each game's GOG app to add them to Boxer. If you are NOT using Catalina, you can download Boxer yourself separately ( ) and run the games with that instead. The difference you note is the difference between Boxer and DOSBox.
Therefore, GOG is updating their DOS games to run on DOSBox instead, which is Catalina-compatible. However, boxer has 32-bit elements and is no longer compatible with macOS 10.15 Catalina and will not run on that OS. GOG's DOS games for Mac used to be run on Boxer. I tried contacting support but I find it difficult to use the form for an issue that concerns the GUI wrapper rather than the game. which can be quite an issue if I want it windowed or something. Menu bar shows application as 'dosbox', no emulation options, no universal keyboard commands, no nothing other than the game. But when installing a new copy from GoG Galaxy or from the GoG website, the GoG wrapper is completely gone. This works on games where I had installed it a long time ago, or copied it from my old Macbook. NicholasH: When running a DOSbox GoG game on Mac, this is the sort of thing that I ought to be able to see: menu bar with emulation options, common keyboard commands, dialog prompts for things like quitting.
