Name suggestion: "Mikes generic platform implementer v1"
By including creators name, less confusion. Generic, not limited. Platform fits both computers and arcades. And implementer avoids the culprint with emulation, simulation etc.. which is not a correct description. Clone might also be nice description.
As for killing of Dennis Minimig. It's like A2000 killing off A500.
With proper module interfaces. The SAME codebase can be used by simple replace the board specific modules. And the whole issue of diverging codebases is eliminated.
Anyway to get a chance at a 68020/AGA (A1200) implementation. A larger FPGA is a MUST.
