Two chips, one old-school meltdown

Advanced Nintendo Entertainment System (ANES) – NES Modded to Use 2 PPUs

Fans are losing it over a wild NES upgrade Nintendo never dared to sell

TLDR: A hobbyist turned the classic NES into a souped-up version with two graphics chips, unlocking flashier visuals on ancient hardware. Commenters are split between amazement, nostalgia, jokes, and one big question: if this was possible, why didn’t Nintendo ever make something like it?

The retro gaming crowd has officially found its latest mad scientist project: a fan-made Nintendo Entertainment System upgrade that stuffs in two picture chips instead of one so the old console can show more colors, more moving objects, and even fancier layered backgrounds. In plain English, it’s someone taking a beloved 1980s game machine and asking, “What if this thing had gone absolutely off the rails?” Even the creator sounds half-amused, half-chaotic, openly warning that the instructions are a little rough and basically wishing brave souls “good luck.” That energy alone had commenters grinning.

But the real fun is in the reactions. One camp is pure nostalgia-fueled hype: one commenter dropped a video demo and immediately started dreaming about an alternate timeline where Nintendo designed the original machine to expand like this from the start. Another commenter brought big “garage inventor” energy, reminiscing about overclocking an old NES at 14, calling it the kind of dumb genius stunt that mostly caused problems—but saying this version is way more exciting because it actually adds something new. Then there was the perfect deadpan comedy entry: “Oh man, A thing I literally needed right now haha.”

The mini-drama? Retro fans are now asking the juicy question Nintendo never has to answer: if the hardware had this hidden potential, why didn’t the company use it? One commenter flat-out wondered whether Nintendo overbuilt the system and then just… never cashed in. Another praised the name ANES, joking that it fits right into old-school emulator naming culture. So yes, this is partly a hardware hack story—but mostly it’s the internet doing what it does best: turning a niche project into a glorious mix of awe, jokes, and “wait, why wasn’t this real?”

Key Points

  • The ANES repository documents a method for modifying an NES to use two RP2C02 PPUs.
  • The project claims graphical benefits including more colors, more sprites, and parallax scrolling.
  • The repository includes schematics and states that KiCad hardware files are available.
  • The bill of materials requires two consoles, with one serving as a donor for components including a second PPU, 74LS373, and 74LS139.
  • The build guide covers board trimming, chip desoldering, capacitor relocation, header installation, dual-PPU board assembly, and demultiplexer wiring tied to CPU address line A12 and the PPUs’ /CE pins.
