Reply To: Modding heat
Likely your best bet, but the uploader hasn’t posted anything too recently so I’m not sure if you would get a reply. Maybe you could have the modded file open alongside the original, corresponding file and looked for what he changed? A pretty primitive suggestion and I’m not entirely sure if it would help with something as seemingly complicated as this, but you could try if you haven’t done so yet.
If all else fails, trial and error is probably going to be your best bet.
