This combines the base game resources with the files of cge_work\dusa and work\ins\usa. This makes both action descriptions and hotspots appear in English, although the introduction credits still appear in Polish. I don't know if this was the case for the original 'official' English release; but I consider it a minor issue.
I've slightly modified the behaviour of the original - rather than prompting each time the user starts for a name, it now only prompts the first time, and uses the entered name as a save description for a slot 0 savegame
