In a similar manner to the the way the XL Engine runs the original Dark Forces game files in an enhanced way, this XWVM mod uses a Unity based engine to interpret and run the original X-Wing game files.
XWVM is a mod to the original Star Wars: X-Wing game from Lucas Arts and Totally Games by Larry Holland and Edward Kilham. Our goal is to rebuild the game engine with newer technologies that allow it to run and make use of the latest hardware and improvements in gaming hardware. The mod will require the player to own and have installation of the original Star Wars: X-Wing game, or have the GOG or Steam versions of X-Wing Special Edition (either the 1993 floppy, the 1994 CD, and/or 1998 Windows edition). XWVM neither contains nor distributes any copyrighted material. All game resource files (missions, voiceovers, SFX, iMUSE automaton, etc) are loaded from the player's copy of the original game, or are original creations of our team, where the original resources are considered inadequate for today's standards.
The mod creator has been discussing iMuse and ship models in the long running XWA Upgrade Project's forums. I wish Azrapse the best of luck with this project - may it one day see the light of day!
