In order to compete with the Minimig on the Amiga-side, the MCC-216 also needs a considerable boost in game compatibility. At the moment, only ~30-50% are working properly. Please note that the compatibility list linked above only lists games which are working or at least partly working.
Arcade Retro Gaming is working an a big improvement step for the AMIGA core.
According to the unofficial MCC forum:http://www.retrorebooted.com/mcc/forum/index.php the work on a brand new very powerful 68000 CPU implementation.
This will be the most powerful 68k ever implemented in an FPGA with a wide compatibility range.
With this they will boost the compatibility to a new level which should exceed the MiniMig implementation.
Can't wait to see this new AMIGA core.
