--- Comment #10 from Fabian Maurer dark.shadow4@web.de ---
It doesn't work on Windows either, which is why the app has to be shipped with DOSBox.
I think that's because 64bit windows doesn't support 16Bit code at all.
FWIW the game seems to run without problems in my XP VM. Not sure if that means XP supports vm86 or that the program doesn't use it.
It also works on otvdm, but that uses emulation.
