Intro

I have ported my old project “pNesX” to the STM32 Nucleo. The pNesX is a NES emulator for the PlayStation that I have created 16 years ago!

Emulation part was almost without change, the sound part was newly added.

Parts

STM32 Nucleo F446RE
QVGA 2.2 TFT SPI (with the SD card slot)
Audio jack(TS or TRS)
USB Connector
Register 100k, 10k, 4.7k, 100
Capacitor 0.01uF, 2.2uF
Breadboard
Wires
Computer Speakers
USB GamePad
