To play Heroes III with the VCMI engine, the original game data and unofficial addons have to be copied (manually) to their required locations. It is not a big issue, but can be confusing at first.
I decided to make things easier and submitted the following to SBo: vcmi-core, vcmi-resolutions and vcmi-wog. Therefore, to set up Heroes III to be played with the VCMI engine on Slackware, just install the following from SBo:
SDL2 SDL2_ttf SDL2_mixer SDL2_image ffmpeg fuzzylite qt5 innoextract vcmi vcmi-core vcmi-resolutions vcmi-wog
If you have the Complete edition from GOG, automatically extract the original game data in your user’s
vcmibuilder --gog /path/to/setup_homm3_complete_220.127.116.11.exe
