Hi all.
I've recently had a clean up in the loft and dusted off masses of my old Atari 8-bit and 486-era PC games stored up there. Now that I've discovered emulators, DosBox and Microsoft's VirtualPC I'm having a blast playing some of my old games.
I've managed to find my bunch of boxed Ultima games and am having a blast playing them but I'm having odd problems with both Ultima Underworlds. I've got them running but the movement seems very odd compared to when I last remember playing them. As I move forward and backward using the S and X keys, I do not seem to be moving in a straight ahead path. Instead, the vanishing point of the perspective implies I'm moving slightly diagonally skewed. Using the Z and C keys makes things even more pronounced that movement isn't quite right.
Anyone know what's cuasing this odd movement behaviour and is there a fix?

There is a known issue with Athlon based processors, from what I recall, and I don't think that there is any fix for that as such. Other members here have experienced the same <a href="http://www.ttlg.com/forums/showthread.php?t=68194&highlight=diagonal">problem</a>.
Personally speaking, I have a pentium and also experience some slight deviation in the movement, but nothing quite as pronounced as the movement in Thief DS :p.

I can't see how this is an Athlon issue particularly, I think it's more likely that it's a bug that's made more pronounced by the speed of your processor. In any case I remember experiencing exactly the same symptoms back on my old Pentium, and possibly even on the 486 I first played the game on.

Bizarre as it sounds, anecdotal evidence did seem to suggest the problem was far more pronounced on Athlon CPUs (or at least the Athlons of a few years back).

Same thing happens to me; doesn't seem to have anything to do with processor speed or architecture, or whether I'm running it in dosbox, dosemu, VDMS, pure DOS, or win32. Very, very annoying.
