Intro¶
I have ported my old project “pNesX” to the nucleo. pNesX is a game console emulator that I 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.
