There were some errors in the emulation code, even in the latest revsion
of dosemu. All I know of (except 1, for which an patch exits on sf.net)
are corrected in the latest svn.
I can run my 32-bit dpmi program and my 16-bit dpmi programs without
op code errors, both in full simulation and in jit mode.
My computer has an Intel processesor, but the bugs were on both
architectures.
