@Hypex, By using a 6502  It doesn't have the $00/01 port, so I can implement that completely in the CPLD.
@Hege, I was thinking more about timing problems interfacing the FPGA with the C16/Plus4 hardware, rather than issues with the software core. When I started work on my 6502 card I really wasn't prepared for how touchy the 264 family are about bus timing.
