====================================================================
This is a quick and dirty port of Nofrendo, a Nintendo Entertainment System emulator. It lacks sound, but can emulate a NES at close to full speed, albeit with some framedrop due to the way the display is driven.
The portation of NES emulator is based on ESP-BSP code and it allows to change the board quickly.
| Selection of the game | Super Mario | Donkey Kong | qBert |

This is a proof-of-concept (only for demo) and not an official application note. As such, this code is entirely unsupported by Espressif.
The games are controlled by USB HID SNES GamePad.
idf.py -p COMx flash monitor
For change the board, please edit the components/esp_nes/idf_component.yml file and change these lines to another BSP component:
ws_7inch:
version: "bsp/7inch_update"
path: "SquareLine/boards/custom_waveshare_7inch/components/ws_7inch/"
git: https://github.com/espressif/esp-bsp.git
For example, you can use this for ESP-BOX:
esp-box: "*"
This NES emulator does not come with a ROM. This demo allows to select between three games, each game must be flashed to right flash region:
- Game:
0x00100000 - Game:
0x00200000 - Game:
0x00300000
You can use this command for flash the game into right flash region:
python esptool.py --chip esp32s3 --port "COM3" --baud $((230400*4)) write_flash -fs 4MB 0x100000 .\games\supermario.nes
