Have a look at the thread I posted about Coldfire compatibility. Looks like there are some essential missing instructions in the Coldfire CPU which means 68k compatibility won't be possible without emulation (=UAE) :-(

Well, I suppose a lot of stuff wouldn't need to be emulated (i.e. custom chips). But emulating a 68k processor on a 266MHz CPU probably wouldn't be much fun, and also may not work for non OS-friendly software.

Why not just physically replace the Kickstart ROM with one which is compatible with Coldfire?
