Just wanted to announce that I managed to get Mortal Kombat 100% working under OS/2. MK had 2 "speed-bugs", which are now removed and special OS/2 / eCS patched-in code to compensate some "bug" (whatever you call it) in OS/2 VDM. MK is using a 16-bit IRQ handler under 32-bit Protected Mode. The VDM simply forgets the IRQ handler that way :(
Now it's working 100% *FULL SOUND* via Soundblaster.
Have fun :)

P.S.: I cannot upload to os2world/games, so please get it from hobbes.
