Essential improvements[edit]

Run in DOSBox[edit]

To improve DOSBox performance, make some changes to the DOSBox configuration file.
Change DOSBox configuration file[citation needed]
  1. Change fulldouble=false to fulldouble=true
  2. Change output=surface to output=opengl
  3. Change memsize=16 to memsize=64
  4. Change blocksize=X to blocksize=4096
  5. Change prebuffer=X to prebuffer=20
  6. Change rate=X to rate=22050

Notes

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.

Recommended Mods[edit]

  • A Patcher: Fixes bugs and can unlock incomplete parts of the game. Effectively XcomUtil from earlier games remade for Apocalypse.
  • RoadWar: Rebalances the vehicle combat, adding more game emphases to it.
  • Karadoc's Apoc Mod: Rebalances tactical missions, can make the both more fair and challenging.
Additional mods and other files for Apocalypse can be downloaded at StrategyCore here.

OpenApoc[edit]

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.

Issues fixed[edit]

X-COM asks for CD[edit]

The Steam version sometimes asks you to insert the CD into the drive. When it does so, the game can't be resumed.
Extract folders from cd.iso and place them in the X-Com folder[2]
The Steam version is set to "Minimal Install" in order to conserver space. If copying files makes you feel nervous you can also run the installer on the ISO and have it overwright the install with the "huge" size.[1] Certain files, such as the music and videos, will still remain on the disk however. You may want to copy these if problems continue.
Use a later version of DOSBox (0.74, Steam uses 0.72)[3]
Easiest way is to copy the DOSBox.exe into the x-com apocalypse SteamApps folder and rename to 'dosbox.exe'
Disable CD check using this, this or this[4][5]
Be sure you performed the first fix first before attempting this one. Note the ISO image is no longer required to be mounted after doing one of these.

Choppy Cutscenes[edit]

Exactly like it sounds, cutscene playback is poor.

Use DOS32A[citation needed]

Bind it to SMKP.EXE with the following command: sb /r Smkp.exe

Replace the builtin player[6]

Use this patch from StrategyCore user Bomb Bloke.

Included smacker player may hang in DOSBox. This can be fixed by upgrading it to the latest version here. Batch scripts may also need to be edited depending on where the game is installed to.

Black screen on startup[edit]

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[edit]

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.
