While it is pretty common for older titles too run too fast under dosbox, I haven't seen an issue like this before. I have lowered the cycles as low as 25, and it still flys through the intro. At 75 cycles the game is basically unplayable. There has to be something going on here, because other games from 82/83 don't run this fast on those cycles. Typically 300 cycles is low enough for any game of that time.

I've tried changing the machine type to pcjr, cga, and such, and I also tried changing machine type to 386_slow, which appeared to be the slowest possible setting.
