and you didn't mention either specifically you had set up a special gus folder, you said you were using the default dosbox settings, those were your words
Firstly, I didn't set it up specifically for this game, it was there from before; and it didn't occur to me to mention that I had installed the GUS stuff previously because I didn't know it was important in this case. Secondly, I wrote that I'm using default settings in DOSBox 0.74 except for certain others that I listed. Those were my words, and I meant exactly what I wrote. The contents of the ULTRASND directory are *not* a DOSBox setting.
and on top of all that, gus sound effects do not need any folder to be set up, only gus music needs a special folder. you can test it with any game that supports gus as the effects driver and it will work every time without any folder needing to be set up, so is completely irrelevance anyway
The GUS driver is apparently designed to support both sfx and music, and the fact that you only want sfx doesn't stop it from wanting to load the GUS instrument patches. Poor design, but you can take that up with the game developers.
Lastly, I suggest you lose the attitude if you want help.
