    Hmm, having Z80 support directly in FPGA would be cool (also for C128 mode, hehe) but it requires FPGA resource then for that ... Anyway if Z80 is implemented, and also have the "hypervisor traps" etc, then it also makes possible to "emulate" other Z80 based computers as well. However, I think it's a bit out of scope of Mega65. Maybe for the C128, it's still somewhat understandable to include, but I hardly believe that it will be included anyway ... It's even interesting to think about on the 65xx line: if "emulation" using "I/O trap" anything makes that possible, other Commodore machines can be "emulated" like C+4 :) But that's at least 65xx ...

    I have got somewhat stalling project to emulate Z80 (well, 8080 for now) on 65xx (namely C64DTV, since it's faster and give more freedom with the help of memory paging and stack+ZP relocation possibility - what also can be done with 65CE02 as well). It'll be *slow* indeed. However if I understand correctly, somewhat "emulation" in used to emulate the 6510 behaviour of C64 in C65GS too in C64 mode, and the CPU speed may allow (with some extra features like linear RAM addressing in 32 or whatever bits?) to do it quite well even from the view point of decent emulated Z80 performance?
