Convert to 128 x 32 screen

[SpeedGP]

Hi, I'm really terrible at this, but I noticed you were using a 128x64 screen, can I just change every instance of 64 to 32 and the 40x40 cups to 20x20 or something like that? Any other issues you can think of?

I'm think about changing Single to purge and also, but haven't decided.

Thanks again for all of your hard work!!
