This game gave me a real-life déjà vu. A few months ago, three friends and I spent a long weekend trying to build a Game Boy emulator from scratch in Rust. None of us had ever worked on emulators before—we basically gave ourselves three days to read the docs, figure things out, and ship something. It was chaotic but also educational and an absolute blast. Encouraging anyone that wants to learn a bit more about simple computers and assembly to try that ! If anyone’s curious about what came out of it: https://github.com/chalune-dev/gameboy

What sort of documentation did you guys review? :)

This isn't a direct answer to your question because I am not OP and I do not know what docs they read but there is a book out called "Game Boy Coding Adventure: Learn Assembly and Master the Original 8-Bit Handheld" that came out last year.

Mostly these two: https://rgbds.gbdev.io/docs/v0.5.2/gbz80.7 and https://gbdev.io/pandocs/

It's incredibly well documented !
