Lost 2 Player Mode

Marble Madness has an unfinished two-player mode. The red marble was fully programmed and behaves the same as the blue marble. Game Genie code 0D0-348-C4A will load the two-player link screen directly after the Midway logo starting a race. The game will return to the main menu if an error occurs with the link connection for either player. There are a few things worth noting about the unfinished two-player mode:

• Player 2 (Red) has a blue timer.
• After player 2 completes a race, the goal will be blue.
• The second player will not be able to enter their score.
• When either player runs out of time, they will be booted to the main menu and the race will continue for the other player.

Game Genie code 00F-B8B-E62 will trigger the placeholder link screen as soon as the first level begins. Neither linked Game Boys will communicate. The reset game function works as intended when Select button is pressed.

Text for the unused two-player mode can be found at 0x535C. This text is unused because the game does not show an additional warning when resetting the game.
