Super Mario Bros. Deluxe

Deluxe features platforming gameplay largely similar to the original, allowing players to control Mario or Luigi through the 32 levels of Super Mario Bros. , referred to in the game as Original 1985 . The game retains the pixel graphics of the original but with a smaller resolution to fit the screen of the Game Boy Color. The game features screen scrolling to reflect this change, and players can use the vertical directional buttons to scroll the screen up or down.

Players can also save the progress of their game at any time. Additions Challenge Mode is an additional mode that allows players to replay completed levels with the objective of achieving the highest score and locating items across the level, including five red coins and a hidden Yoshi egg in each level. Players select individual levels and complete them in a single attempt. Upon completion, Toad will provide the player with a rating based on their performance in reaching a threshold score, collecting the five red coins in a level, and discovering the hidden Yoshi.

The Vs. mode allows two players to compete in a race to the end of a level by using two Game Boy Colors connected with a Game Link Cable . Vs. levels feature vanishing blocks that can be triggered by a player to hide or reveal obstacles.

A similar single-player mode titled You vs. Boo is available where the player races Boo across the same courses. In this mode, when players complete a level, Boo's speed is set to the best time set by the player. Players are able to unlock additional game features and collectables through completing several actions in the game.

The main addition is the ability to play Super Mario Bros. 2 when the player reaches a minimum score of 300,000 points in the original mode. Other unlockable features are included in a Toy Box menu. These include a calendar that allows players to set marks or notes for dates between 1999 and 2999.

The fortune teller allows players to select one of five cards, with the results reflecting levels of luck, providing extra lives the first time they receive an Extremely Lucky card. The Yoshi Finder scrolls through random levels and displays a frame in which a hidden Yoshi can be found in the Challenge mode. As players progress in the game, they will collect awards, pictures and banners that can be printed using the Game Boy Printer .
