ESP32-NESEMU, a Nintendo Entertainment System emulator for the ESP32

This is a quick and dirty port of Nofrendo, a Nintendo Entertainment System emulator. It has basic sound support, but can emulate a NES at close to full speed, albeit with some framedrop due to the way the display is driven.

Warning

This is a proof-of-concept and not an official application note. As such, this code is entirely unsupported by Espressif.

This code is an esp-idf project. You will need esp-idf to compile it. Newer versions of esp-idf may introduce incompatibilities with this code; for your reference. esp-idf test work well version: v3.3-rc-dirty
