I use UTM on a Mac and built an iso of the game attached to cdrom and installed
to c:. Ran the game and sound worked but I was in a loop as I couldn’t figure
out what the fire button was in the game. This was on a stock FreeDos 1.4
build. Underneath the hood UTM uses Qemu so it should work if you load FreeDos
under Qemu.
YEAH! SOUND!!!
Just casually I've discovered that it exists a fork of SBEMU called
VSBHDA and it is bundled in FreeDOS 1.4 under the directory
"C:\FreeDOS\DRIVER" so I gave it a try and it worked!!
In VirtualBox 7.2.6 I've set the "ICH AC97" sound card that it was
detected by VSBHDA (also SBEMU detects that sound card but it didn't
work). Here the fdconfig.sys and fdauto.bat files with the working setup
for Space Ace:
