Pokemon Emerald Ported to WebAssembly (100k FPS)

some weeks ago I made a Gameboy emulator from zero in rust and then exported it to wasm

https://holy-lake-f6df.sdreyesg.workers.dev/

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

Likely because all of the external docs were already in its training set.

Yes, this project was made in around 15 hours of Codex.

how much docs did you need to supply?

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)
