HOW THE SNES GRAPHICS SYSTEM WORKS

Summary from the TLDR Web Dev newsletter

This article goes into the four chips responsible for the SNES (Super Nintendo Entertainment System) graphics system: the two Pixel Processing Units (PPU1 and PPU2) and two SRAM chips. The PPU1 acts as the brain, while the PPU2 acts as a compositor to display the visuals. The article then discusses the different types of RAM used for storing graphics data, including VRAM (which is designed uniquely), OAM, and CGRAM.
