Dunno, but try with very low cycles (below 1000) and the normal
core, and with sound disabled.
And you could see if using loadfix helps.

loadfix doesn't help. I've tried with cycles down to 800 or so. At that point, the game would be absolutely unplayable anyways, but it still doesn't work.

I would suggest trying normal core (or dynamic or full if you're already using normal)

Also, try unplugging your joystick (if you're using one) to see if that helps.

Playing with DOSBox's memory emulation may also have an effect.

Also, could your installation be corrupt?

Hey wait. I have X-Wing as well. I run on Windows XP (SP1), and Xwing still works fine on my comp without dosbox. Were there other versions of Xwing?

Yeah, there were a bunch. I'm trying to get the dos cd version working (with bwing addon). You probably have a windows version. I'm also running linux.. so the windows version wouldn't really be easier for me.

There was first a DOS floppy version, with two optional expansions: Imperial Pursuit and B-Wing.

Then there was a DOS CD-ROM version (possibly two of them? Dunno)

Then there was at least one Windows version.

Personally I prefer the DOS versions because they don't have the annoying loud engine noise, and they use MIDI for the music, resulting in music that takes advantage of my MIDI hardware and that reacts much better to the action. The downside is that it runs in 320x200 instead of 640x480.

Did anyone figure this out?

I have the same problem with the same game, and also with Tie Fighter Collectors Edition. When the mission is supposed to start, it dumps to DOS with the message "Divide by zero".

I had this working a few months ago, with the exact same config, but I may have updated to a new version of DosBox. I'm currently running v0.65 on Gentoo linux.

I have tried a lot of things with Tie Fighter:
- The three possible cores (dynamic isn't a valid choice here, apparently).
- Cycles from my regular 22000 down to 200.
- Sound disabled both in dosbox and in game.
- With and without joystick.
- I have no idea what loadfix is, but i tried "loadfix tie.exe". Didn't help.

A little side note: DosBox has given me countless hours of fun, so thanks a lot to all the devs and those who help out on the forums. If I get more spare time next semester, I hope I can help out somehow. I'm a programmer, and I love my old dos games. =)
