note ~0003903

JOTD (developer)

there's an illegal TRAPEQ instruction here, so I guess that slave does not work on a machine below 68030.

I'll rewrite the slave one of those days (it's very old OSEmu/JST emulation crap, and I cannot even recompile it)

note ~0003908

JOTD (developer)

OSEmu emulation module has a 68020+ specific instruction.
Migrating to KickEmu solved the problem
