I have ported my old project “pNesX” game console emulator to the nucleo.
Dependencies: SDFileSystem mbed
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.

Limitations
- Since the rest of the RAM is about 50kbyte, maximum capacity of the game ROM is about 50kbyte.
- The length of the file name up to 32 characters.
- The number of files in the folder is up to 100.
Used Library
