Read Configuration article on project Wiki.
To easily install a DOS game from GOG to your Steam library, use included script:
$ ./install-gog-game ~/Downloads/setup_warcraft_orcs__humans_1.2_\(28330\).exe
It will unpack the game to ~/.local/share/games
, prepare a setup that works around all
known Steam bugs and generate .desktop
file to be added to your Steam library. After
that you can play the game using steam-dos or Proton.
Installation script depends only on Python standard library, you can put it in your PATH or wherever you like.
steam-dos preconfigures selected titles to turn MIDI music on/off, depending on user preferences. Supported games are:
- STAR WARS™ - Dark Forces
- STAR WARS™ - X-Wing: Classic Edition
- STAR WARS™ - X-Wing: Collector's CD-ROM Edition
- X-COM: UFO Defense
- X-COM: Terror From the Deep
- Jagged Alliance Gold
- Jagged Alliance Deadly Games
- System Shock: Classic
- The Ultimate DOOM
- Final DOOM
- DOOM II
- Master Levels for DOOM II
- Heretic: Shadow of the Serpent Riders
- Hexen: Beyond Heretic
Just click "Play" and enjoy glorious MIDI music, there's no need to hunt those
pesky SETSOUND.EXE
programs.
Sythesiser running does not automagically turn on MIDI music in every game,
sometimes you need to enable it manually (usually there's a file called SETUP.EXE
,
IMUSE.EXE
or similar somewhere in the game directory). Use following settings:
Music/device: Roland MPU401/General MIDI, Music Port: 330
If you'll find a game, that supports MIDI and you need to enable it manually, create a bug report, please!
Some game collections on Steam use "Sierra Classics Launcher" graphical frontend.
There's no support for graphical version of this launcher - the first game in a collection
will be started by default. You can select different game to run with SDOS_SIERRA_GAME
environment variable.
For example, to start King's Quest 6 from King's Quest Collection:
SDOS_SIERRA_GAME=6 %command%
Check SierraLauncher.ini
file in game's installation dir to learn which number
corresponds to which game.
