The game works, I tested it before creating this listing, but it is a bit finicky. You might have to remove and reinsert the cartridge a few times to get it to work. The method that worked for me every time was pushing the cartridge in from the bottom left corner. It is a very fun game! Very nostalgic if you grew up playing Tetris! Please reach out with any questions or offers. Will be shipped with care!
