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

 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.

 To control the NES, connect a Playstation 1 or 2 controller as such:

-Pin    GPIO

-CLK    14
-DAT    27
-ATT    16

 Also connect the power and ground lines. Most PS1/PS2 controllers work fine from a 3.3V power supply, if a 5V one is unavailable.
