For those squares at the bottom to qualify as squares, they’d have to be… you know… squares.
You don’t put a chess board on a round table and say the area around the board is another “square” do you?
Incidentally, that’s why square tables are banned at the highest levels of play.
Oh jeez. I forgot about that. I had that running on my DS back in the day from a GBA flashcart with a big-ass CompactFlash card sticking out the bottom. Good times.
