Notes on testing:

A multimeter was in testing for internally connected pins. MM read 0.000 ohms for internally connected pins and also read the same value for pins with that were connected with a switch (when the button was pressed).

A pulldown resistor was connected as well as a resistor in series with the input GPIO pins (10k and 470 ohms).

The buttons were tested with the commits in this issue. The results were also observed with piscope: "UP": 12, "DOWN": 16, "LEFT": 20, "RIGHT": 7, "SELECT": 8,
