It, and the coal-c one must be in the .ja (jet compressor method file) in the UTC files, i tried using a tool named JAX (Auran Jet Extractor) however it cannot open the ancient UTC .ja's only the more recent ones like trs2004 - trs2012. So instead I tried downloading Fileviewer software made in 2001 and supposedly could open .ja files, it probably was what the devs used but idk, however when I tried to use it, it gave me an error about some old crap, probably because a 2001 software shouldnt be running on windows 11, so tomorrow ill try downloading a virtualbox to see if i can get that software to work.
