In the title description, it says that it includes:
"Includes STAR WARS™: TIE Fighter and STAR WARS™: TIE Fighter - Defender of the Empire, 1994 (DOS), 1995 (DOS Collector's CD-ROM), and 1998 (Windows) versions, and STAR WARS™: TIE Fighter - Enemies of the Empire 1998 (Windows)."

In the requirements side, it says it works on:
"Works on: Windows (7, 8, 10, 11), Linux (Ubuntu 14.04, Ubuntu 16.04, Ubuntu 18.04), Mac OS X (10.7.0+)"

Are Linux ports included? Or are there instructions on how to install and run these in Ubuntu (14, 16, or 18)?
