The actual emulator code lives here (all in STB-style headers):
https://github.com/floooh/chips
The chips-test repo has the 'integration' code which assembles the headers into executables:
https://github.com/floooh/chips-test
There's also a similar project in Zig (but less complete, it's more like an experiment what the same implementation ideas would look like in Zig) that might be a bit more readable and with everything in one place:
https://github.com/floooh/chipz
E.g. start reading the top-level emulator executables:
https://github.com/floooh/chipz/tree/main/emus
...and then move your way down to the system implementations:
https://github.com/floooh/chipz/tree/main/src/systems
...and finally to the chip emulators:

Thx for those links!
I see references to files in a "chips" directory. For example "chips/m6502.h". But those are missing? Where can they be found?
Like the concept! Reminds me somewhat of simulating a design in a hardware description language (eg. Verilator). Or the concept of 'drivers' in MAME (dunno if those emulate cycle-by-cycle btw).
So I'd welcome the opportunity to dive into how it's done on a code level.
