Hey there.
Alien Rampage which has DSS support doesn't seem to detect it. I'm using Picovox in DSS mode at port 378h, which otherwise works fine in Wolf3D and Duke3D.
When I choose it in the menu it just does nothing. Couldn't find any ways to set the port. The game has no setup program.
Does anyone have any ideas how to make it work?

It shows this message for a split second.
