What kinds of problems? I'm surprised by the fact
that DOSbox (officially,
apparently) is only for games, because DOS games play all kinds of evil tricks
with the hardware and you'd think once they work, pretty much everything would

I don't know this -- it's just an educated guess -- but AIUI DOSbox
emulates /DOS as well./ It's aimed at running games and focuses on
emulating a games-compatible DOS environment, hardware and software
both.
Bochs emulates an x86 PC and runs a copy of real DOS. It doesn't focus
on super-accurate hardware emulation of sound etc.
DOSemu does neither: it's a VM designed to run a copy of actual DOS
under Linux, with drivers to bridge between the Linux filesystem and
DOS and so on. So, no emulated hardware: no emulated disks or
anything, just ordinary files in a Linux directory. Compatibility
moderate, but your program can access the Linux filesystem.
I use DOSemu (very occasionally) for running DOS apps such as
WordPerfect and MS Word for DOS on my Linux machines. Works well but
is a little finicky about screen modes and so on.
I don't really play games any more, but I've experimented with DOSbox
for this and it worked well.
I've tried booting some elderly OSes in Bochs as an experiment, but
frankly, these days, VirtualBox does this so much better and is
freeware - in fact it's all FOSS except for the extension pack that
adds some niceties like USB2 support for Windows XP and later.
