@renova:
Tested on WinUAE with 68000 / 2MB Chip / 8MB Fast / FullECS and Classic Workbench 3.1, it works just great 
So, it should even work on a Mist board.
Thanks, Lionel and Laurent
I would not trust WinUAE on comparing CPU speed. I tested my "Marco" CD32 game using UAE and the speed was not comparable. The game run much smoother and better on WinUAE then on real CD32.
It's better to test it on real machine.
