If you haven't already, it might be worth checking out TIE Fighter Total Conversion. It's a fan remake of TIE Fighter built on a massively modded X-Wing Alliance engine that works well on modern computers. It has a pretty faithful recreation of the original TIE Fighter (plus collector's CD content) campaign, and a reimagined version of it using things that weren't possible in the original game engine. https://www.moddb.com/mods/tie-fighter-total-conversion-tftc

You'll need a copy of X-Wing Alliance (available cheap on gog) to run it.
