Tetris & Dr. Mario ROM

Tetris & Dr. Mario shares a similar design to the respective NES versions of the games included while featuring music from their Game Boy versions. In Tetris, players must use different types of falling tetrominoes to form complete lines from the left to the right of the playfield, without any holes between them. Completed lines will disappear and cause any blocks on top to fall towards the bottom. Players can rotate the blocks to place them in specific spots, and can also hold down to make them fall faster. Once all the blocks reach the top of the screen, the game will be over. Tetris includes the “A-Type” and “B-Type” modes from the Game Boy version, alongside a head-to-head multiplayer mode.

In Dr. Mario, players must use colored pills to defeat the viruses littered around the playfield. Viruses come in red, yellow and blue, and must be eliminated by matching two or more same-colored pills either horizontally or vertically. These pills can be one solid color or a mixture of two, one on each side. Pills can be rotated around, and can be dropped faster by pressing down. Once all the viruses have been cleared, the player will move onto the next stage. The game will be over if the pills reach the top of the screen. Dr. Mario features a two-player mode where both players must compete against each other to clear the stage of viruses.
