Ultima Underworld: The Stygian Abyss is part of the Ultima series, where the Avatar is brought back to Britannia for the sole purpose of being falsely accused of kidnapping a girl. It was a technical advancement by being one of the early 3D games, although the gameplay mechanics were not exactly ideal with plenty of skills being considered useless or redundant.

Essential improvements[edit]

Patches[edit]

The Ultima Underworld 1 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 as well.

Solutions For Ultima Underworld I: The Stygian Abyss ...

Run in DOSBox (retail)[edit]

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

Ultima Hacks mouselook patch[edit]

The biggest change is the addition of mouse-look (looking around by moving the mouse), which can be toggled on and off with a keypress. In support of this, the allowed range of vertical view angle has been greatly expanded, and the 3D rendering engine has been hacked to have it draw the bits of the world that become visible when the player looks sharply upward or downward.

Also, spell runes can be typed directly (with Ctrl+Alt+<letter>), without having to navigate through the inventory and the rune bag.

Things made more convenient:

  • The opening title-screen or cinematic is skipped.
  • The player's heading is not adjusted when moving against a wall.
  • Skill points gained in training are immediately reported in the message log (currently only in Ultima Underworld II).
Save

A number of keys have been added or changed as listed on the patch website.

Untima Underworld I +2 Save Editor?, Page 1 - Forum - GOG.com

Apply the mouselook patch (Windows GOG.com release)[4]
  1. Extract the contents of <path-to-game>game.gog to a new directory, located at <path-to-game>game.
  2. Upload <path-to-game>gameUWUW.EXE to the online patching tool.
  3. Save the patched file over the original.
  4. Locate <path-to-game>dosboxULTIMA1_single.conf and replace its contents with the following (back up the old conf file first) to make DOSbox run from the unpacked iso that you patched. Simply revert the config file to make it run from the unpatched exe.

Underworld Exporter[edit]

Use Underworld Exporter to play in higher resolutions, add mouse look, listen to higher quality/custom music, etc.
Some bugs still remain.
Can also be used to play Ultima Underworld II: Labyrinth of Worlds, but it is only partially supported at the moment.
Set up Underworld Exporter (Windows)[citation needed]
  1. Download and install the latest Github release.
  2. Find config and open it with your text editor of choice.
  3. Find Path_UW1= and place the path to your Ultima Underworld installation folder after the “=”.
    • That is, the folder with CRIT, CUTS, DATA, etc.
    • Note: All paths must end with a trailing slash . Ex. C:pathtofolder
  4. To add music, download Music.Packs from the same location as the releases and extract. Afterwards, go into config, find UW1_Soundbank=, and then place the path to the folder containing your music of choice after the “=” .
    • The music pack gives one the choice between MIDI, Soundblaster, and PSX (PlayStation 1) versions of the OST.
    • One can use their own music files if they are in .ogg format.
  5. To use with the GOG.com version of the game, one must extract the files from game.gog; the folder UW is all one needs.
    • One method is to rename the file from game.gog to game.iso and then extracting the files using WinRAR or 7-zip.

Issues fixed[edit]

Piano footstep sounds[edit]

Ultima Underworld Editor - Release : Ultima

The GOG.com version's sound is incorrectly configured by default to use the Roland MT-32. As the Roland MT-32 predated General MIDI, the sound effects will not match with what's normally expected.[5]

If you have issues with audio coming from one speaker or headphone, replace 2 7 220 1 sound with 4 -1 -1 -1 sound
Manually change audio settings (Windows)[5]
  1. Go to DATA in the installation folder.
  2. Edit UW.CFG
  3. Replace 6 -1 -1 -1 sound with 2 7 220 1 sound
  4. Save your changes.

Notes

This fix will also change the music's quality.
You can also adjust these settings using INSTALL.EXE or UWSOUND.EXE if they are present.
Manually change audio settings (OS X)[5]
  1. Go to Finder, Applications, Ultima Underworld 1+2.
  2. Right click Ultima Underworld 1 and choose Show Package Contents.
  3. Open Contents
  4. Open Resources
  5. Right click Ultima Underworld 1.boxer and choose Show Package Contents.
  6. Open C Ultima Underworld 1 and 2.harddisk
  7. Open UNDEROM1
  8. Open DATA
  9. Edit UW.CFG with TextEdit (right click, Open With)
  10. Replace 6 -1 -1 -1 sound with 2 7 220 1 sound
  11. Save your changes.
Configure DOSBox MIDI to use Munt[6]
  1. Download and Install Munt.
  2. In DOSBox command prompt, type mixer /listmidi to view the devices.
  3. In the configuration file, under section [midi], change midiconfig=0 to match the associated listed midi id (usually 1).

Notes

Munt requires the Roland MT-32 ROM which is not distributed in the same package. As an alternative, it may also be possible to try an alternate Software MIDI with a soundfont similar to the Roland MT-32.
The Roland MT-32 has support for reprogramming sounds. Therefore installing a soundfont-based MIDI and using an equivalent soundfont may not be an ideal solution in the general case.

Sluggish and/or jumpy mouse controls[edit]

The cursor may jump around in-game or mouse control may feel sluggish (especially on menu screens). To fix the first issue, disable joystick functionality; to fix the second, increase mouse sensitivity.
Fix jumpy mouse cursor (Windows)[7]
  1. Go to the installation folder.
  2. Edit dosboxULTIMA1.conf
  3. Set joysticktype to none
  4. Save your changes.
Fix sluggish mouse (Windows)[8]
  1. Go to the installation folder.
  2. Edit dosboxULTIMA1.conf
  3. Change sensitivity from 100 to 200. Experiment with this figure until your mouse feels right.
  4. Save your changes.

Windowboxing/black borders on all sides[edit]

By default, DOSbox does not scale to fullscreen vertical resolution, leaving black borders around the entire view area. This fix removes the black borders on the top and bottom, leaving only black borders on the left and right due to the original 8:5 aspect ratio
Fix fullscreen windowboxing[9]
  1. Go to the installation folder.
  2. Edit dosboxULTIMA1.conf
  3. Under [sdl], set output to ddraw and fullresolution to 0x0.
  4. Save your changes.

Notes

  1. File/folder structure within the installation folder reflects the path(s) listed for DOS and/or PC booter 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).
