Game Boy pixel pipeline explorer

The Game Boy pixel pipeline explorer is a development tool that visualizes the step-by-step operation of the original Game Boy’s PPU, breaking down how each pixel is rendered from background, window, and sprite layers. It is designed for emulator developers and hardware enthusiasts seeking to understand or debug the intricate rendering process. The tool is interesting because it demystifies a notoriously complex subsystem, making the PPU’s behavior transparent and interactive.
