I worked on a cgdarirte emulator for the NES many years ago when I was just getting into FPGAs. had an FPGA, some flash, some SRAM, and card-edge connectors for NES, SNES & N64. We got the SNES and N64 working, and managed Tennis on the NES but with snowy graphics.The problem with NES of course is the asynchronous buses. Unfortunately we only had a single bus for the flash/SRAM on the board so the only option was to time-multiplex the two NES buses. We could generate a clock up to 80MHz on the board. I started looking at the timing in more detail but moved on to emulation of complete systems before I got to far into it. IIRC the access pattern on the CHR bus was actually less random than appeared on 1st glance and I deduced it would be possible to cache some data in the FPGA in order to reduce the number of accesses to flash/SRAM.I really should re-visit that project. I know a lot more about FPGA design now than I did back then. We got around 6 PCBS made and two boards assembled and it cost around AUD$1,000. Unfortunately we took a short-cut and used a custom DC-DC converter from another project and we have no more of those. Won’t make that mistake again! But the two boards should still be working.
