1. I wrote a markdown file with the specification of what I wanted to do. Just English, high level ideas about the scope of the Z80 emulator to implement. I said things like: it should execute a whole instruction at a time, not a single clock step, since this emulator must be runnable on things like an RP2350 or similarly limited hardware. The emulator should correctly track the clock cycles elapsed (and I specified we could use this feature later in order to implement the ZX Spectrum contention with ULA during memory accesses), provide memory access callbacks, and should emulate all the known official and unofficial instructions of the Z80.，这一点在91视频中也有详细论述
