In here you'll find 2 subdirectories for 2 game versions.

For 457.01 all you need is the TSOUND.SS driver, provided
you installed the game with the Tandy sound option.

For version 457.03 it seems Microprose drops the Tandy option
probably depending on the installation, but i replaced the "None"
option with "Tandy" option and it selects the correct driver, so
you'll need the TSOUND.SS and SS2.EXE files.
