The NES, like most home computers of its era, had a 6502*. As it turns out the simplest "Arithmetic Core" I could imagine is comparable in power to the 6502!

What I described had some more memory, & less instruction-decoding logic. Yet a full barrel-shifter to aid crypto! How exactly does it compare, & how'd I emulate the 6502 on it?

To start to handle the amount of RAM the NES had I'd need to enable our AC's "harvard-mode".

* Rather Ricoh 2A03, I'll come back to that...
