Why not build hardware-based dynamic recompilation (or translation) into the execution pipeline, i.e. an MC68000 compatible ISA that translates only the necessary bits to the ColdFire ISA (the "microcode," so to speak). Could such a solution be faster than a complete recreation of the MC68000 ISA in an FPGA? Or could a solution that translates from one ISA to another, e.g. MC68000 to ARM, be just as fast or faster?

The sarcasm, it stings! It stings! ;-)

FPGA-based solutions seems to be the best if one insists on 68K compatibility., look at the NATAMI/Minimig/ActionReplay boards.

That wasn't exactly what I had in mind. I was thinking more or smallish FPGA or some other piece of hardware that looks like a 680x0 but actually functions as a memory controller, instruction cache, translator, etc. It's probably easier to just wait for a faster FPGA solution and use an existing core.
