The Linux version of Fallout 1 is actually the DOS version which uses DOSBox in order to play it. It was exclusive to Desura store and it is no longer available. The same is also true for the digital release of the Mac version, though the retail version was a true native port.
A demo is available.

Essential improvements[edit]


Patch v1.1 updates the game to the latest version.

Fallout 1 High Resolution Patch[edit]

1024x768 resolution using the Fallout 1 High Resolution Patch v3.0.6
1024x768 resolution using the Fallout 1 High Resolution Patch v3.0.6

A utility/patch that modifies the game in memory to add support for windowed mode, higher resolutions, and various other enhancements.

Can also be downloaded as part of the Fallout Fixt mod compilation.
Included with the GOG.com and Steam releases.

Further details can be found in the official thread.

Fallout Fixt[edit]

A mod that patched the game to enhance, expand and improve upon the Fallout 1 experience.

Patch compilation which contains several essential patches and bug fixes, allows for high and widescreen resolutions, and contains optional fan content.
Appears to be outdated compared to more recent mods, and has gone unmaintained for years.
Introduces gameplay changes, as opposed to just fixes, that change the vanilla experience - even when selecting the "Purist" option at installation.
Contains well documented bugs that can make progress impossible, and have yet to be fixed. [1]

Updating to the latest version of Crafty's Sfall is recommended as the included version is out of date. The latest version includes new bugfixes and optional features, set the following in the new ddraw.ini for compatibility:

Editing ddraw.ini for Crafty's Sfall[citation needed]
  1. Open ddraw.ini.
  2. Set the following code:
Even the latest version of Sfall1 still suffers from several known crashes.

4K Ultra HD
Fallout Fixt patch allows 4K, but it is not recommended. Text becomes too small to read, and there is no improvement to graphical quality relative to lower resolutions. Consider using Lossless Scaling in windowed mode instead.
Field of view (FOV)
Use D3DWindower or the Fallout 1 High Resolution Patch.[3]
Borderless fullscreen windowed
Use Fallout Fixt or Fallout 1 High Resolution Patch and in f1_res.ini set "WINDOWED=1" and "WINDOWED_FULLSCREEN=1"
Anisotropic filtering (AF)
Anti-aliasing (AA)
