DID's EF2000 crashes when loading a level in Doxbox 64bits, but it does not in Doxbox 32bits (or at least in Linux).
I was puzzled about this as recently installed the game and it wasn't working at all so I tested 0.65, 0.72, 0.73, 0.74 and svn 64bit versions, none of then worked, and I clearly recalled that 0.73 worked fine in the past and took me a while to notice that last time I was using 32bit Linux. So I downloaded the Dosbox 0.74 32bit package for my distro, and when I extracted it and added the missing 32bit required librearies, it worked out of the box.
Might be interesting to test if the "core" setting has an influence on this.
I have tested it, and what I have found is the following:
On 64bit dosbox:
normal and simple core works ok.
auto and dynamic core does not.
On 32bit dosbox.
Any core setting works fine.
Also I have seen that in 64bit dosbox with auto and dynamic cores, the game runs for a second, then dropbox output 'segmentation fault' and closes.
