A few of the games in Gold Box series from SSI limited Tandy sound effects, to only when Tandy sound is selected. I managed to alter the executable files, to allow Adlib or Roland MT-32 music, to be combined with the Tandy sound effects. The changes are quite simple, I just altered the code to use Tandy sound effects in all cases, except when PC Speaker is specifically selected.

The changes are based off Buck Rodgers: Matrix Cubed 1.0 and Champions of Krynn 1.2. I hope they are useful to people.

All the other games in the series, seem to allow Adlib for the introduction music under DOSBox, even when Tandy is selected for sound.
