A long time ago I added an opcode to the 6809 and 6309 cores in MAME
that would cause the emulation to stop and breaking into the MAME
debugger. They would never accept such a change so I posted it on my
website.

At some point the CPU cores were completely rewritten and my patch
didn't work anymore. But Erik Gavriluk ported them over with a bunch
of other additions to his MAME fork:

All his stuff is good, but I only need EMUBRK:

The opcode is $113e.
