This is my implementation of mos6502 cpu core, version used in nes (without decimal mode). i don't think it anything better than other existing cores, but here we are.

Just looked at the source, I find it fascinating to read even though I can't really understand much of it. Maybe one day I might be able to get just a little bit of it. π

Awesome!! You have even written it in a sane HDL (I'm not a big VHDL fan π). I also like the simple single file approach π When I have time I will try to compare it with other HDL implementations. Also comparing it with the Visual6502 netlist behaviour will be interesting π

This is fantastic! I can see 6502 chip replacements =D I thought about using my own 6502 emulation core to replace a 6502, this is way better!!! Stick a configurable NOP generator or a way to test address certain ranges - makes it much easier to test address decoding!
