You must use XBOX 360 ISO Extraxt to unpack or repack the .iso.

.ARC UnPack/RePack

To UnPack: Simply drag and drop an .arc file onto arctool.exe, and it will unpack its contents into a folder with the same name as the original .arc file.

To RePack: Run a command prompt and type "arctool.exe -i "nameoffolder" "nameofarc.arc"" without quotes.

For example: C:\Users\User\Desktop\arctool.exe -i player player.arc. ("player" being the folder and "player.arc" being the name of the file after packing.)

Make sure that arctool.exe is in the same location as the folder that you'd like to repack or else the above method won't repack.

.LUB Decompilation

  • 1. Place ChunkSpy.exe into the xenon folder.
  • 2. Create a text file there with the following code:
for /r %%i in (*.lub) do (
  chunkspy "%%~dpni.lub" > "%%~dpni.lua"
  • 3. Rename the file extension to .bat and run it.
