Ufo Enemy Unknown

Official Bugfixes and PatchesOverview

DOS (Patch 1.2)

1. You have to start a new game to make the changes effective.
2. Only the memory address and the DMA channel have to be selected in the setup. For some people the selection of the IRQ had led to an error
3. This patch includes a newer version of the Dos extension DOS4GW. In earlier versions there were sometimes problems with the old version.
4. Failed headings sometimes caused multiple images to be displayed at once. This is now fixed.
5. The action points are set to a maximum of "80", thus solving another problem.
6. The variety of missions is increased, now all mission types that exist can occur.
7. The alien intelligence is increased, so the game becomes a little more challenging.
8. The UFO encyclopedia is extended to include missing entries.
9. The broken file: UBASE_07.MAP will be replaced with a correct version. So there are no more problems when starting a mission with this map.
10. There is no PC Speaker Support anymore for UFO.
11. The bug with the environment memory is fixed.

DOS (Patch 1.4)

1. new sound effects and music files. This patch changes the sound effects, e.g. when clicking a button or when an alien dies. From an acoustic point of view, these files are better, but there are many fans who prefer to swear by the old files. So it's a matter of taste who uses which sound files. These sound files are also used in the CE ( collectors Edition).
2. You can change the music volume with the "+" and "-" keys on the number pad while you are in the geoscreen (globe) and when you are in the tacti area (insert).

Fan Bugfixes and Patches

(all versions)XCOM UTIL (bugfixes only)

1. INSTRUCTION:
   This part describes how to use the X-COM Util to fix bugs without changing the whole game. The problem is, that when executing the file XcuSetup.bat besides the changes of the difficulty bug the settings for the bases and the spaceships are changed. There is now a possibility to change this file so that only the bugs are fixed without changing the game. Download this version of XcuSetup.zip and overwrite the original file from XCOMUTIL. Then only the bugs will be fixed and the rest of the changes can be ignored.


2. One recognizes also with the start of XCOMUTIL what is changed. The following lines appear in the unmodified version:
   Patch Applied: Ship statistics set from XCOMUTIL.CFG
   Patch Applied: Difficulty levels enabled
   Patch Applied: Area data set from XCOMUTIL.CFG
   Patch Applied: Disjoint bases fixed and new maps added
3. You can also modify the file very easily. Just open the file XcuSetup.batin an editor and search for the line xcomutil ufoexe shp:cfg map:cfg wrt XcuSetup (CTRL+F).
   Then you have to change this line to xcomutil ufoexe wrt XcuSetup and only the bugfixes are made and the copy protection is removed. But be careful, always pay attention to upper and lower case, otherwise the whole thing won't work.
4. After the change the whole thing looks like this:
   Patch Applied: Difficulty levels enabled
   Patch Applied: Disjoint bases fixed and new maps added
   Who doesn't feel like making the changes themselves (really not much work) can download the modified file here.XcuSetup.zip
5. You can read the original description here:
