Play Sega Master System games On ESP32 Espressif Systems

Sega Master System emulator running on an ESP32
Performance looks awesome for only one core being used...
This is a port of #Sega_Master_System to the #ESP32 chip.
It will run most Sega Master System roms at full speed .
(However, because of the low speed of the SPI LCD used and the overhead of pushing pixels to it, the frame rate is limited to 15-20FPS for now.

Display
To display the output, please connect a 320x240 ili9341-based SPI display 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,

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

Pin GPIO
CLK 14
DAT 27
ATT 16
CMD 2
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.

ROM
This emulator does not come with a ROM. Please supply your own and flash to address 0x00100000
