NES Reloaded: A Touchscreen Gaming System Inside a Cartridge

A childhood icon reborn as a full-featured gaming console — inside the cartridge itself.

NES Reloaded: Touchscreen Gaming Cartridge

What started as a random idea – “could I fit an entire gaming console inside a single NES cartridge?” – turned into one of my favorite nostalgia builds yet. NES Reloaded is part art piece, part emulator, and part childhood time machine.

 

At its core is an Android 14-based device that started life as a dedicated MP3 player. It now runs a fully redesigned interface running EmulationStation + RetroArch, neatly CNC-fit behind a screen window where the cartridge label once lived. The “blow port” is now home to USB-C power and a headphone jack, with volume and power buttons tucked into the side. Pair it with an 8BitDo Micro controller and you’re instantly back to 1987 — minus the dust and cable spaghetti.

 

When idle, it cycles through a slideshow of my old cartridge labels and LEGOCade Mini gameplay clips, doubling as a tiny living display of pixel memories. There’s even a Cassette Mode for playing The Beatles, because why not let nostalgia have a soundtrack?

My NES Playlist

Game On

What started as a simple NES cartridge mod turned into a fully self-contained Android-powered console. Using an AGPTEK T08X (Android 14) MP3 player as the brain, I CNC-milled a precise window where the cartridge label once was — now the 4″ touchscreen display.

 

The system runs:

  • Slideshow of NES cartridge labels from my childhood
  • LEGOCade Mini gameplay reels (see post for details)
  • Cassette Mode — a Beatles-themed audio player with visualizer
  • EmulationStation + RetroArch — for Atari 2600 and NES classics
  • Android Game App with Archive.org integration — for experimental ROMs
  • Paired with a 8BitDo Micro controller

🔈 Hidden Joy

When docked or charging, it cycles through NES label slideshows and gameplay clips — turning nostalgia into ambient art. Unplug it, pair the controller, and you’re instantly back in 1987.

Like most of my builds, NES Reloaded sits somewhere between invention and memory — a tiny time capsule built to spark joy. It reminds me that nostalgia doesn’t have to live behind glass; it can be powered on, tapped, and played.

 

This cartridge now lives on a shelf alongside the LEGOcade Mini, Mini Mac, and other “what if?” experiments from my Cabinet of Curiosities — each one reimagining a bit of the past with modern parts. It’s a reminder that creativity doesn’t need a grand plan — sometimes it just needs a spark, a tool, and something worth remembering.
