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 :)

Brilliant work, does the visualization handle the pixel FIFO timing quirks that make PPU emulation such a joy to debug?
The PPU is always what separates a solid GB emu from a buggy one. That FIFO timing is brutal to debug. What'd you build this with, raw Canvas or WebGL? Visualizing the pipeline states like this would've saved me so many headaches back when I was implementing mine. Really clean tool.
which PPU revision is this modeling
mid-scanline mode switches handled?
visualizing the ppu pipeline like this makes it way less intimidating
