DIY portable NES Emulator for less than 25$

Links to components, drivers, source code etc. in this description.
In this video I'll show you how to build a portable NES Emulator.
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.

Source Code:
mine: https://github.com/MittisBootloop/esp32_nesemu_wemosmini

If you want to build one on your own, but don't want compile the Source Code, you can download the following zip-File, it contains all needed files + a little manual "How to Flash". You can also download the circuit schematic:
