Die space for m68k on FPGA?

[Fats]

DosBox with 68k Dynamic Recompilation should be able to achieve 386 emulation speeds on a fast 68060 or fpga 68k CPU. The bonus is that the Amiga can multitask at the same time kind of like the advantage of ShapeShifter over a real 68k Macintosh.

Why not go for both a m68k and x86 CPU core at the same time on the FPGA ?

Better would be to add specific instructions to the 68k that help with emulation of other processors.

For the use case of running DOSBox in AmigaOS on an FPGA, I personally think it is more efficient to get rid of the whole complex JIT emulation in the first place. Of course just a matter of opinion.
