Tennis cartridge exploit
A cart-swap exploit that allows the player to access Super Mario Bros. glitch worlds, documented by Japanese gamers and published in Family Computer Magazine.
It involves removing the Super Mario Bros. cartridge while the power is still on, replacing it with Tennis, tossing the ball twice and serving, and then walking a specific number of steps.
Next after replacing the cartridge with Super Mario Bros. again, continuing the game with A+Start will allow the player to access a glitch world based on how many steps the player made in Tennis.
