Essential improvements

Run in DOSBox

To improve DOSBox performance, make the following changes to the DOSBox configuration file:

  • Change fulldouble=false to fulldouble=true
  • Change output=surface to output=opengl
  • Change memsize=16 to memsize=64
  • Change blocksize=X to blocksize=4096
  • Change prebuffer=X to prebuffer=20


If you still suffer from poor performance, try changing cycles=auto to cycles=max.
You may need to use Ctrl+F11 and Ctrl+F12 to control the speed of DOSBOX's emulation.

OpenApoc

An open source reinterpretation of the game's engine that's currently in a pre-alpha state.

Further details can be found on the project's official website, GitHub repository, and project forums.

X-COM asks for CD

The Steam version sometimes asks you to insert the CD into the drive. When it does so, the game can't be resumed.

Black screen on startup

This game has issues with certain SVGA cards (both real and emulated). It can be fixed by using this patcher. Note this program requires Windows and will not run in DOSBox.

Game hangs after entering the Alien Dimension

Certain versions of the game shipped without the map files for the Alien Dimension. They can be downloaded here.

Notes

  1. 1.0 1.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/7660/ in addition to or instead of this directory. The app ID (7660) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
