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.
将豆腐切成麻将大小的方块，轻轻埋入柏树灰中，让其酣睡一夜。这个过程中柏树灰将豆腐完全浸渍，豆腐在柏树灰中尽情呼吸，吸收其间的矿物质和碱性成分，同时挥发部分水分，为炒制做准备。浸渍一夜，时长刚刚好。
