Thanks for the hint, that sounds full of interesting knowledge ;)
You can open and extract the new mac installers (dmg files) with any packager, so the new mac
installers are kind of our zip-files we wanted ;-)
Well, as far as I remember, extracting DMG files on Linux is a real pain in the bash. Innoextract (for .exe setups) is much more convenient than mount ;)
At the moment not every game using scummvm
or dosbox is available yet for mac, but it's very likely gog will add them later. While it's hard
to make the old mac games run on the new mac os you can assume that every old game (not the indie or other newer games) available for mac are using dosbox or scummvm. With Fallout and MDK there
are also games that use the dos-versions for the mac installers while the original releases
are windows versions.
There you have point.
Still, my original request wasn't only for the sake of being convenient : it would be a rather nice recognition to the authors of said utilities if GOG showed (even if through obscure lists) what games are using them.
