NES game emulator

Classic NES game emulator, take us back to childhood!

Or... Let us find a way to let it play itself!

1. Function

1.1. init(rc_type=nes.KEYBOARD, cs, mosi, miso, clk, repeat=16, vol=5)

Initializes the NES emulator

Parameters

• tc_type： Remote control type, keyboard（nes.KEYBOARD） （The serial port communicates with the computer's keyboard, it's not directly connected to the board's USB port...） or PS2 joystick（nes.JOYSTICK）。

  A PS2 joystick is recommended for a better experience. Serial communication can't send more than one key at a time. If you want, you can try to write your own scripts here
