A chip8 emulator port for raspberry pi pico with VGA out
The code was made originally for the Adafruit Feather RP2040 beacause that the wiring is like this:
- Columns of keypad matrix are connected to 7 - 10 GPIO pins.
- Rows of keypad matrix are connected to 26 - 29 GPIO pins.
- HSYNC pin is gpio 24.
- VSYNC pin is gpio 25.
- RED, GREEN and BLUE pin are 18, 19, 20 GPIOs respectively. They needs 330 Ohms resistors.

- Van Hunter Adams for VGA pio library.
