When I Played this in the 90s there was background music during the missions. The Gog version doesn't seem to play music during the missions or trainings. Any way to get mission background music back?

Got it working myself! So happy! Here is what I installed and in what order.

1. Tie Fighter Reconstructed Music Patch

2. No Music fix(I used the link in the last post.)
