Thank you for your interest Dubious. Currently I am opening the XComGame.upk with HxD from the following location: /XCom-Enemy-Unknown/XEW/XComGame/CookedPCConsole I search for the original hex code that was posted by Amineri and see the given offsets on the left. There are 7 rows of offsets for that particular code that I searched (the hex number is 7 rows long, and there is a different offset listed for each row, the offsets are 8 digits long). Unsure of which it would be, I have been going through each one and replacing the 'OFFSET=' field in my custom mod .txt with each of the values systematically. No luck so far, always crashes on launch. I then replace XComGame.upk with the original and try the next. Was getting curious if I was doing the whole thing wrong. Most everything I was reading on hexidecimal wiki and other forums, didn't really help with this, so I came back here to see if I missed something. As requested, here is my current .txt custom mod for Toolboks that I was working on. I used the examples that were given with Toolboks for reference. I noticed the examples all use 7 digit offsets, while I see 8 digit offsets in HxD (not sure if that matters).
