Pre-packaged with DOSBox.[3] Includes Ultima Underworld: The Stygian Abyss.
macOS (OS X)

Essential improvements[edit]


The Ultima Underworld 2 Patch is needed for floppy disk versions. The CD-ROM and GOG.com versions are already fully patched. An unofficial General MIDI patch is available here.

Run in DOSBox (retail)[edit]

To run correctly in DOSBox change cycles=auto to cycles=max.

Ultima Underworld Portable[edit]

Package made for owners of the GOG version of Ultima Underworld 1 and 2, it has an easy to use launcher and incorporates community made mods

Easy to use launcher.
Comes with DOSBox Staging, a modernized version of the original DOSBox, so the emulation is much better than the DOSBox version that the GOG release offers.
Roland MT-32 support incorporated by default, which means high quality music when compared to Sound Blaster and sound effects that plays properly.
Provides community made mods like the mouselook patch from Ultima Hacks, a portuguese translation and a modified shades.dat, all in one package.
Has an extraction tool that installs the game if the required GOG file is found on the same directory of the extractor.
Requires Windows, does not work on Mac nor Linux. Config files and mod components can still be used.
This is not a native application, it still relies on emulation.
Only the game.gog file is required, just copy it on the same to the same directory where the extraction tool is located that both Ultima Underworld 1 and 2 will be installed.
The files from the CD-ROM release can be used, but it will be needed to extract them manually in the required directory, since the extractor cannot extract the CD iso.

Issues fixed[edit]

Piano footstep sounds (GOG.com)[edit]

The GOG.com version's sound is incorrectly configured by default, resulting in misplaced effects such as piano sounds for footsteps.[4]

  1. Choose Game DOS Settings at the menu when starting the game.
  2. Press C to confirm the hard drive to use.
  3. Use the keyboard arrow keys to go down to Sound Blaster Pro, then press Enter.
  4. Press Enter four times to confirm the other default sound settings (these do not need to be changed).
  5. Press Y to confirm your changes.
  6. Press any key twice to finish saving your changes.

  1. 1.0 1.1 File/folder structure within the installation folder reflects the path(s) listed for DOS game data. For the GOG.com release, file changes in DOSBox are redirected to <path-to-game>/cloud_saves/ even if GOG Galaxy is not used (this folder contains all redirected files, so some files in the cloud_saves folder might be temporary files or other files that do not contain saves or settings).
