There are several reasons to patch your Jedi Knight and Mysteries of the Sith. These are unrelated to the 3D Acceleration Fixes, which are simply additional .DLL files that are added to your Jedi Knight or Mysteries of the Sith Installation Folders.

Patching your Jedi Knight and Mysteries of the Sith requires two things.
  • Using a patcher utility to modify your JK.EXE or JKM.EXE
  • Adding some new files to your Jedi Knight and Mysteries of the Sith Installation Folders (New Dynamic Link Libraries for JK.EXE and JKM.EXE)
Important Note: LucasArts has released only one patch, v1.01 for Jedi Knight. We strongly recommend again using because The JK Unofficial Patch for JK.EXE will NOT work if you have the v1.01 version of JK.EXE. However, the JK Unofficial Patch does include LucasArts's v.1.01 fixes.

The JKHUB.NET distribution of the JK Unofficial Patch requires you to use their patch utility to modify JK.EXE. Many users have reported issues with this patch utility corrupting their game executable. After using patcher.bat users may recieve the following error when attempting to launch Jedi Knight: "JK.EXE is not a valid Win32 application". Because of this issue we are choosing to distribute an ALREADY patched JK.EXE to avoid this issue. 

The Jedi Knight Unofficial Patch consists of the following files:
The Mysteries of the Sith Unofficial Patch consists of the following files:

Installing Jedi Knight Enhanced and Jedi Knight Retexture Pack
Jedi Knight Enhanced is a massive graphical improvement to Jedi Knight's models. Additionally, Jedi Knight Retexture Pack makes enormous improvements in quality to Jedi Knight's textures. Both modifications require the JK Unofficial Patch. Jedi Knight Enhanced is currently distributed by JKHUB.net with an outdated version of the JK Unofficial Patch, and the Jedi Knight Retexture Pack does not include it at all. We have combined these two Jedi Knight modifications in a single zip archive for convenience. We also have developed easier installation instructions for users.
