Hi,
I built the console and it works well.
Unfortunately, I am the exact opposite of Art
I do love electronics, but on the software side i only do what i have to do to get it running.

Tetris works perfectly, but at Snake the keys are swapped by -90 °.
I hold the console horizontally and have soldered the buttons directly to the board.
So if I want to go right, I have to press the top button.
If I want to go left, I have to press the lower button.
If I want up, I have to press the left button.
If I want down, I have to press the right button.

For clarification, here is a picture of what the buttons are doing.


Hopefully someone can change the v3 for me so that it fits.
I would be very grateful!
