I attempted to extract "uPl00ChrisCos3.arc" (Xbox 360 Version) with the dmc4.bms and it didn't work. I decided to change the all the endian littles to endian bigs on the script. It extracted incorrectly but I found a file which did extract correctly pl000.mtg (The rest were all corrupt 0KB)
I wanted to know if it was similar to the PC version pl000.mtg here is what they look like in Hex editor.
XboxPCXbox| 00 47 54 4D = GTM.
PC | 4D 54 47 00 = MTG
Bytes such as 00 00 00 01 on Xbox are 01 00 00 00 on PC
Bytes like 3F 80 00 00 are backwards on the PC version 00 00 80 3F
Bytes like 00 01 00 0E are each moved to the left once 00 0E 00 01
Seems that the one file extracted correctly then; Can someone find a way to extract everything correctly?
I've also found .LLC .RTEX .MTG Files that extract fine in other .arcs
