Mortal Kombat Fitgirl repack.
I'd use Lutris for that, it's a rather automated process, you create a new entry, it asks for the installer, and usually recognises the correct executable for the game.
Literally just setting up docker to then install HA.
Personally, I prefer to run HA in a VM rather than Docker, especially if you're experimenting, IIRC with docker installation it doesn't support backup and restore of components and their settings. Virt-manager makes running VMs easy enough.
