Mechwarrior 4 and Mech Paks
Just want to clear up a few things:

The Filenexus release of Mechwarrior 4 (2 CDs) works just fine with Th3_Lorax Mech Paks.

Even when it appears that the Mech Paks fail the safecast check during installation (DOS box, schd.exe, insert CD message,...) it still works! This is because you will run the game with the cracked .exe!

There's a post on Filenexus Forum about updating (patching) Mechwarrior 4 to version 2. Just copy this link to your browser:

*Note: You don't need to create a .bat file like the guy did. You can manually copy the file (Follow the steps). You also don't need to download the Patch 2 or the crack since these are included in the Black Knight Expansion release.

Here's how to get the mech paks to work with Mechwarrior 4 and Black Knight Expansion:

1. Install Mechwarrior 4 (Full Installation)

2. copy "D:\Content\Movies\*.*" "C:\Program Files\Microsoft Games\MechWarrior Vengeance\content\movies\*.*"
copy "D:\Content\Movies\Op1Mpeg\*.*" "C:\Program Files\Microsoft Games\MechWarrior Vengeance\content\movies\Op1Mpeg\*.*"
copy "D:\Content\Movies\Op2Mpeg\*.*" "C:\Program Files\Microsoft Games\MechWarrior Vengeance\content\movies\Op2Mpeg\*.*"
copy "D:\Content\Movies\Op3Mpeg\*.*" "C:\Program Files\Microsoft Games\MechWarrior Vengeance\content\movies\Op3Mpeg\*.*"
copy "D:\Content\Movies\Op4Mpeg\*.*" "C:\Program Files\Microsoft Games\MechWarrior Vengeance\content\movies\Op4Mpeg\*.*"
copy "D:\Content\Movies\Op5Mpeg\*.*" "C:\Program Files\Microsoft Games\MechWarrior Vengeance\content\movies\Op5Mpeg\*.*"
copy "D:\Content\Movies\Op6Mpeg\*.*" "C:\Program Files\Microsoft Games\MechWarrior Vengeance\content\movies\Op6Mpeg\*.*"
copy "D:\CONTENT\SHELLS_1\FILES\stutte_1.wav" "C:\Program Files\Microsoft Games\MechWarrior Vengeance\content\shellscripts\files\StutterShark_ music.wav"
copy "D:\resource\*.MW4" "C:\Program Files\Microsoft Games\MechWarrior Vengeance\resource\*.*"
copy "D:\resource\missions\att.txt" "C:\C:\Program Files\Microsoft Games\MechWarrior Vengeance\resource\missions\att.txt"
copy "D:\resource\missions\koth.txt" "C:\C:\Program Files\Microsoft Games\MechWarrior Vengeance\resource\missions\koth.txt"
copy "D:\MW4.exe" "C:\Program Files\Microsoft Games\MechWarrior Vengeance\MW4.exe"
copy "E:\RESOURCE\MAPS\*.*" "C:\Program Files\Microsoft Games\MechWarrior Vengeance\resource\maps\*.*"
copy "E:\RESOURCE\MISSIONS\*.*" "C:\Program Files\Microsoft Games\MechWarrior Vengeance\resource\missions\*.*"
copy "C:\Program Files\Microsoft Games\MechWarrior Vengeance\MW4.exe" "C:\Program Files\Microsoft Games\MechWarrior Vengeance\copy MW4.exe"

(You basically have to copy everything from the 2 CDs to the corresponding directories on your hard drive)

3. Install Black Knight Expansion. This will automatically run patch 2. DON'T COPY THE CRACKS OVER YET!

4. Install Inner Sphere Mech Pak and/or Clan Mech Pak. It will also automatically run patch 3. Now extract those cracked .exe (the ones included in Th3_Lorax releases)

5. Run "MW4_v30_nocd.exe" to play Mechwarrior 4, "MW4x_pr1_nocd.exe" to play Black Knight Expansion.

The best part is that both "mw4.exe" and "mw4x.exe" are intact (not cracked) so you won't have to reinstall everything when a new patch comes out. You also don't need the CDs to play.

A few months ago, there was a post on this forum about how to disable C_DILLA. Just use the search to find it.

Thanx to Th3_Lorax for the releases. Peace out!
