Earlier, the clean up and updating of the PCGamingWiki Warcraft: Orcs and Humans Page article page on the PCGamingWiki was completed.
(The PCGamingWiki is a crowd sourced game fixing and information aggregating website.)

In the article, there's information about the features supported by different versions of the game, improvement mods for the game, and possible fixes for problems you may have encountered.

The Wiki is always looking to expand and include more information.
If you would like to check out the article, or contribute fixes for issues you have been able to fix, you can check it out at the link below.

Also DosBox page and DosBox fixing issues.
GOG video settings are mismatch (do not include hotfix) from Mac. And mismatch very old other DOS games build. It miss some important options in UI. Better check DosBox page and read what every option do in DosBox included .conf (config) files. Every.
Also HOTFIX for MAC change one default option. That, again, also should be for WIN build - but its not. Just reset what GOG put to defaults: resolution, output, aspect ratio. Read carefully what option do. And do not try to doce game widescreen (no aspect ratio) - that broke proportions obviously and make image more blured. As in any natievely-4:3 games. And do NO force unlimited FPS, just like in every games.
