Very cool! I know it is slow, but very cool none the less!
And yes, I'm sure with more work, things could be fleshed out, improved upon, and sped up, but it always requires time, help, and patience, and that is sometimes the tricky part.
Sorry, didn't mean to dog your efforts.

I can tell you a bit about the project. In fact I can tell you everything about it. I'm the guy who did it.
In regards to speed, I did it really fast and in my spare time. In raw performance it may not be so impressive but if I was going to optimize it could be much faster.
Having a job takes away from the time to tinker on it.
But I agree that porting over 68k Aros to run on ColdFire would be beneficial.
Also note that the ColdFire V4 chip is running at 200mhz and the emulation is a little less than half its speed. If it were a faster chip the emulation would also be faster.
