And if anyone wants to know why it won't work.... I'm done my homework on the subject. There's a small number of instructions that exist on both 68K and Coldfire, but each executes them differently. It's possible to trap 68K instructions that are invalid for coldfire and "reroute" them. Using this trick make the two about 99.8% compatible. Trouble is these other instructions are not invalid, can't be trapped and will cash Amiga code because of the way they operate. Also there's an issue with I/O differences.
One suggestion I had for the coldfire dev group back in the day was to run dual processors. One to prescreen code, make changes if necessary then feed the corrected code to the second processor. Back then coldfires were not very fast so basically doing JIT compiling would have killed performance.
These days I'm thinking porting one of the Amiga like OS's to cheap dual core 1GHZ ARM processors would be a fun project. Picture this... Core_1 doing JIT recompiling and feeding Core_2 that's running a "softcore 68K" emulation. Piece of cake, I should have all that done in what.... two weeks?

I think the Atari Coldfire developers will disagree with you. They have a Coldifre processor running just fine and have already produced hardware. See:
http://acp.atari.orgAnd who said 99.8% compatibility isn't "good enough"? All the major operating systems have dropped a slight bit of compatibility with older software as time progressed. That's true with Windows, Linux, OSX, etc.....as well as with AmigaOS. The only thing that will satisfy the irrational people here who insist on 100% compatibility is a time machine to take them back to 1985. I would welcome ANY OS that has 99.8% compatibility with software written for previous versions.
It's funny how the detractors here say that Coldfire can't be done yet they ignore the fact that an entire Amiga, nay several Amigas, can be fully emulated on a processor as alien as an x86 with better than 99.9% compatibility. I for one can live without those few programs in that .1-.2% range. And why couldn't UAE be ported to run on a Coldfire processor? That's a rhetorical question......
