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.
