On my config, I have my DOSbox set to Auto on Emulation Core, and then Max on CPU Cycles. If that doesn't work out for you, try setting Emulation Core
to Dynamic. If that does work, but makes the game run too quickly, just press the - or = sign buttons (next to the backspace key) from within the game,
until you have your desired run speed.
Hopefully that'll get the game running for you. Just remember to set your CPU Cycles to max. For some reason 15,000 cycles doesn't work for me either, or
any amount of cycles higher than that.
