I have adjusted the HIMEMX line so it does not load when you select Menu
2. This allows JEMMEX to handle everything (XMS + EMS + UMBs) without a
conflict, which should be the most stable way to get Space Ace running
with sound and expanded memory.
Thanks, improvements, the game now starts (previous it freezes), but
still with no sound. I can play, but reached a change of scenario the
screen gets scrambled and I can exit the game by pressing the ESC key.
I run FreeDOS 1.4 inside VirtualBox 7.2.4 I chose "Intel HD Audio" as
soundcard for the virtual machine. The SBEMU driver was bundled in
FreeDOS so I used that, not the one on GitHub.
Follows my fdauto.bat and fdconfig.sys any hints?
