ColdFire Project?

And probably won't be updated at all. There's much consent here that a Coldfire creates major problems in software compatibility and seems to be no good choice for the Amiga, running legacy software. It's not impossible, but once you've mastered all problems, it's probably not much faster than an '060 - if at all.

Of course, that would provide a tremendous speed increase. But you'd have to recompile, which isn't an option for the vast amount of legacy software. Another way would be a patch database, but I doubt the user base could reach the critical mass for that.
For the emulation option it's a lot smarter to start with a faster and more readily available CPU like a cheap & fast x86.

One day someone will do an '060 simulation in FPGA. In the VERY far future...
