Alternatively, you could have downloaded an existing one. What you did is just a roundabout way of acquiring one of the many WASM Rust GB emulators in the training set. Except it probably now has several problems from reconstruction. You didn't learn anything new from the process. It's just wasteful in several ways.
bro, I learned a lot, I did it step by step and discussed everything with Claude, then used the knowledge to build an emulator at work for a rtos machine (WIP)

took me 3 hours with Opus. Opus knew the whole ISA, clock, bus quirks, etc. from their training without any external docs
