I made Ben Eater's 8-bit breadboard computer Emulator in C++
I wrote an emulator for my own 6502-based computer, in C:
https://github.com/DavidBuchanan314/6502-emu/
The hardware design was largely based on http://searle.x10host.com/6502/Simple6502.html - the 6850 UART is the only peripheral that is emulated.
The CPU implementation is "complete", and passes various 6502 test suites.
Looking back, there's one big thing I'd like to improve - all memory bus accesses should be done through a getter/setter function, which implements the address decoding logic to decide whether the access should be directed to RAM, or a peripheral. The current implementation of peripheral access, iirc, is a bit of a hack.
