ESP32 Game Playes with NES

Play NES Game with sound, emulate a NES to full speed, albeit with some framedrop due to the way the display is driven.

Warning

I can not tell you what and how any more.

Compiling

This code is an esp-idf project. You will need esp-idf to compile it. Newer versions of esp-idf may introduce incompatibilities with this code;

Display

To display the NES output, please connect a 320x240 ili9341-based SPI display (or ST7735.) to the ESP32 in this way:

=====  =======================
Pin    GPIO
=====  =======================
MISO   25
MOSI   23
CLK    19
CS     22
DC     21
RST    18
BCKL   5
=====  =======================

(BCKL = backlight enable)

Also connect the power supply and ground. For now, the LCD is controlled using a SPI peripheral, fed using the 2nd CPU. This is less than ideal; feeding the SPI controller using DMA is better, but was left out due to this being a proof of concept.

Controller

To control the NES, connect TM1638 with key as such:

======  =======================
TM1638    GPIO
======  =======================
STB     4
CLK     16
DIO     17
======  =======================

If you want to get software reset key,connect Button with key as such:

=====  =====
K      GPIO
=====  =====
RST    27
=====  =====	

Also connect the power and ground lines. TM1638 Only Support 5V VCC.

Sound

Also connect to PAM8403 etc:

=====  =====
Pin    GPIO
=====  =====
DAC    26
=====  =====

ROM

This NES emulator does not come with a ROM. Please supply your own and flash to address 0xF0000. You can use the flashrom.sh script as a template for doing so.But ROM must be smaller than your (Flash Size - 1MB).

Other

Prohibit commercialization,except for 52Pi.
