I'm trying to get Silent Service 2 running for my father, who absolutely adores the game. I found SS2 and downloaded it, and got the latest version of DOSBox. I can get it to see SS2, and start up the game's command prompts, where it asks you whether you have a joystick, and if you want digital voice, but then it just quits, with runtime errors

run-time error R6003
- integer divide by 0

run-time error R6001
- null pointer assignment

R6003 shows up if we choose yes to digital speech, and doesn't if we choose no. No biggie, we can do without the "Aye aye sir!" R6001, I'm guessing, has to do with us choosing No for a joystick, but we have no joystick to use!

Any help would be immensely appreciated!
