Very neat. The only down side I see is the price of these Minimeg boards. I still find it a lot easier to just run UAE over spending all the money needed for one.
Absolutely! The cost of the board, and other extra hardware, is perfectly ok with me since I view it more as paying for the entertainment value in hacking the board and less so for actually using it.
The Minimig board do have some benefits (and drawbacks) compared to UAE but considering the cost I'd say UAE is likely the better choice for most people.
My Intel Macbook Pro runs UAE very well for playing classic games, but it doesn't quite have the coolness factor of running on 68K+FPGA hardware controlled from a PPC MorphOS computer :)
