This should be reallll interesting...

If you ever do write this 'converter', I recommend doing a few benchmarks.
Unless you spend a lot of time working on optimization, I suspect you'll
find that a decent C compiler/optimizer beats your converted 68000 code by
a fair margin.  The MIPS C compiler knows all about the cpu pipelining,
instruction overlaps, register scoreboarding, branch delay slots, and on
and on.  Will your converter?
