A Nintendo Entertainment System Emulator for the ESP32
Mitti has built a portable NES Emulator based on the inexpensive dual-code ESP32 microcontroller, with a total build cost of less than $25 USD. They write:
I used an ESP32, an ili9341 Display and a Battery. All this components are placed in a NES-Controller. It is based on the Nesemu Source Code from Espressif. I’ve made some changes, now it’s possible to choose between a bunch of Roms that have been flashed to the ESPs internal memory. Also one can open a little menu with some settings like sound, brightness or fullscreen.
See GitHub and Youtube for more info on this great build.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
