It is also somewhat rare to find, which makes treasure hunting for it even more thrilling!

These three chips are called the CPU, PPU1, and PPU2. When Nintendo revised the SNES motherboard around 1995, all 3 of these chips were combined into one single chip called the S-CPUN. This hardware change is what gave this model of the SNES more graphics processing power.
