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.
The FastAPI webapp Python code is good with logical integration of HTMX routes and partials, but Opus 4.5 had fun with the “YouTube-themed” aspect of the prompt: the video thumbnail simulates a YouTube thumbnail with video duration that loads an embedded video player when clicked! The full code is open-source in this GitHub repository.

This is all very tedious, formulaic, and difficult to write, so it is typical to generate this glue automatically using tools like embind or wasm-bindgen. This streamlines the authoring process, but adds complexity to the build process that native platforms typically do not require. Furthermore, this build complexity is language-specific; Rust code will require different bindings from C++ code, and so on.
