Many guides regarding this topic are several years old and i recon that there might have been some changes here and there.

Here's the deal:
I just discovered Munt and was eager to play around with it.
I actually got it to work in Wing Commander by changing the Midi Device ID in the DosBox config and set the game config to Roland ( All thanks to PhilsComputerLab [url=]https://www.youtube.com/watch?v=xRrSlvL9oCQ&t=686s&ab_channel=PhilsComputerLab[/url] )

I read some forum posts and it seemed that its the same routine with pretty much every other game as well.
Set the device ID in the DosBox config, launched MM3's config file (which was already set to Roland & Blaster) and...nothing. Soundblaster Music.
Switched Munts ROM files to CM32...nope, same deal.

Am i missing something ?

EDIT:
Well, the issue solved itself.
Turns out, even though the game config was already set to "Roland + Blaster", i had to confirm it anyways.
The issue was my german keyboard layout (Y and Z switched).
I pressed y and nothing happened, which i interpreted as "it warned you about not installing the game, just changing the settings, so thats probably why confirming doesn't do anything" and just ESC'd out of it.
Pushing Z helped :P

Silly solutions to stupid problems !
