Homebrew Need to find out the color of a pixel at a specific point for my Snake port

[AsadSolos]

Hi guys,
I'm making a port for snake on the 3ds for fun and I'm trying to see if there's a way to get the color of a pixel on the top screen of the 3DS at a point. Reason why is that I need to find a way to stop the game when the snake goes over itself, and the only way I can think of is having something in my main while loop that says that when the snake goes over a pixel that is green colored, the game should end. I don't really know if theres a function that can get the data of a specific pixel, and more specifically the color. If there is one, please let me know

i'm not sure if you can read the screen directly, but you could try saving the board state in a matrix. where 1 represents a snake block, and you add one to where the snake head is, and if it adds up to two, the snake hit itself.
