I made a pixel pipeline explorer for the original Game Boy's Pixel Processing Unit (PPU). If you are implementing a Game Boy emulator or just interested in it then this might provide some help :)

Could you build this?
Partial The interactive debugging UI can be vibe-coded, but cycle-accurate simulation of the Game Boy Pixel Processing Unit's fetcher and FIFO pipelines requires niche hardware emulation knowledge.
What it would actually take: The core simulation requires cycle-accurate modeling of the DMG PPU: the 8-pixel FIFO, sprite multiplexer, OAM search, and tile fetcher state machines with exact hardware timing. The stack is typically written in low-level TypeScript/Rust compiled to Wasm, demanding specialized knowledge of Game Boy hardware registers, LCD timing quirks, and emulator design.
