Super Mario Bros. Deluxe

Super Mario Bros. Deluxe, released on the Game Boy Color in May of 1999, was a remake of the 1985 Super Mario Bros. and 1986 Super Mario Bros.: The Lost Levels games. It was released fourteen years after the original Super Mario Bros..

The game received critical acclaim for a number of reasons, including: bringing back the original Super Mario Bros. for a whole younger generation to experience, especially to a handheld that allowed players to enjoy Super Mario Bros. wherever they went, the inclusion of the previously-rarely seen Super Mario Bros.: The Lost Levels, and the great abundance of featured unlockables.

Plot
Because Super Mario Bros. Deluxe has several games and modes built in, the plot varies from mode to mode. The plots for Super Mario Bros. and Super Mario Bros.: The Lost Levels are exactly the same as in their original releases, but have additional features unlocked when beaten.

Super Mario Bros.
When Bowser kidnaps Princess Peach, ruler of the Mushroom Kingdom, Mario and Luigi must set out on a dangerous adventure to rescue the fair princess. As they trek across multiple locations to get to Bowser's Castle, they encounter massive ambushes of enemies along the way. Though their adventure starts out easy, it grows progressively harder as the brothers travel closer and closer to Bowser's Castle. Eight massive worlds stand between them and the princess, and they will do whatever it takes to rescue her from the foul King of Koopas.

Super Mario Bros.: The Lost Levels
Just after Mario and Luigi had rescued Princess Peach from Bowser, he kidnaps her once again. This time, however, Bowser hides in a more secluded location, amidst a mass amount of dangerous worlds for the Bros. to travel. Though the worlds seem familiar to the Bros., they are much more dangerous and inhabited by more enemies than they had ever experienced before. Yet, the Bros. march forth through nine dangerous worlds. When they finally reach Bowser's Castle, they will defeat him and rescue the fair princess once more.

You vs. Boo
After collecting 100,000 points, Boo challenges Mario and Luigi to a race. The Bros. must race against Boo through various courses, eventually beating him. Though Boo has the advantage of being able to travel through solid objects, he can be defeated.

If the Bros. do so, Boo runs away and is replaced with a Green Boo. This Green Boo moves much faster than his predecessor.

However, if the Bros. defeat this Boo in a race as well, he ventures off and is replaced by a Pink Boo. This Pink Boo is extraordinarily fast, and poses quite a challenge for the Bros.

Eventually, if the Pink Boo is defeated in a race, a final Black Boo challenges the player. This Boo is the fastest of all the other Boos. Even though it is an extremely tough foe to overcome, the Bros. eventually defeat him and claim victory over all Boo racers.

Original 1985
This is the first mode of the game that the player will encounter. It is a near-exact replica of the 1985 edition of Super Mario Bros., having only a few changes. The player will once again have to travel through eight worlds, each containing four levels.

Differences Between Super Mario Bros. and the Port

 * Many glitches from the original game were taken out of Super Mario Bros. Deluxe. As such, well-known glitches such as World -1 and Small Fire Mario cannot be performed in this game.
 * The player can save the game at any time.
 * A world map has been added for each world, displaying the player's progress in the game.
 * The player can switch between Mario and Luigi at any time, simply by pressing the 'Select' button on the overworld.
 * Water and Lava are animated, rather than being motionless.
 * Luigi, Toad, and Peach have new animations.
 * Luigi's sprite palette has been changed. In the original, Luigi wore a green shirt with white overalls, and Fire Luigi wore a red shirt with white overalls, looking identical to Fire Mario. In Super Mario Bros. Deluxe, Luigi's palette was changed to reflect that of Mario's. As such, Luigi wears a brownish-green shirt with green overalls, and Fire Luigi wears a green shirt with white overalls.
 * Various sounds were added for various actions that were silent in the original. For instance, the Jumping Board makes sounds when Mario jumps on it, a sound is made whenever Lakitu tosses a Spiny Egg, Mario makes skidding sounds when he reverses while walking (much like in Super Mario Bros.: The Lost Levels), Cheep-Cheeps make a noise before they jump, and finally, just as in the Super Mario All-Stars version, a chime or buzz will sound depending on whether or not Mario takes the right path in castle levels.
 * Being a smaller screen, it doesn't show the entire level (which adds a degree of difficulty in stages like 1-3). Plus, players can go back only a little bit.

Challenge
This mode allows the player to travel through all thirty-two levels of Super Mario Bros., only this time, he or she must collect Red Coins and Yoshi Eggs. Depending on how well the player does in the challenge, his or her score may vary greatly. The player can also unlock many pictures and awards to view in the Toy Box if he or she does exceptionally well. In each level, several regular coins are replaced with several Red Coins; when the player collects the Red Coins, the Red Coins are tallied. However, to collect the Yoshi Egg, the player must hit a block that is hidden somewhere in the level; this block contains the Yoshi Egg.

Super Mario Bros. For Super Players
When collecting a total of 300,000 points in Original 1985 mode, the player automatically unlocks Super Mario Bros.: The Lost Levels. The game isn't an exact port of the original, as some modifications have been made. World 9 through D have been eliminated from the game. The wind feature was also removed; as such, the game was modified so that some jumps were actually possible. Graphics were updated very slightly, mostly in the sprites palettes. The player can also play as Luigi in this mode, just as he or she could in Original 1985 mode.

You vs. Boo
After the player has earned a total of 100,000 points in Original 1985 mode, he or she will automatically unlock You vs. Boo mode. This mode is extremely similar to Versus mode in multiplayer, only this time, the player must race against a Boo. The Boo has a major advantage over the player, as it can pass through walls an obstacles without slowing down. The player will have to race against the Boo on a particular stage. Each stage is modeled after a certain level in the game, only with some modifications. Springboards and blocks inhabit the courses mostly, as the player is required to utilize these to traverse the course successfully. There are four different colored Boos to race against, each noticeably faster than the last.

Versus Mode
This mode is almost the same as You vs. Boo. By utilizing the Game Boy Color Link, two players can race head-to-head on a particular level. The levels are laid out identically to those featured in You vs. Boo mode. Only two difference can be found between Versus mode and You vs. Boo:
 * Boo will not be found on any level as competition.
 * The players can rearrange blocks to complicate the level for his or her opponent.

High Scores
This mode isn't a game mode. By utilizing the Game Boy Color Link, two players can view and exchange each other's high scores on levels and game modes.

Toy Box
The Toy Box contains a large variety of different toys for the player to use. The majority of the items in the Toy Box must be unlocked, generally through game completion.

Fortune Teller
The Fortune Teller is a bonus mode that is accessible from the very start of the game. The player enters the Fortune Teller, pick a random card, and receive a fortune. There are five different varieties of fortunes: Extremely Lucky, Very Lucky, Lucky, Unlucky, and Extremely Unlucky. The only way that the Fortune Teller can actually affect gameplay is if the player receives a Extremely Lucky fortune and starts a new file; he or she starts the new game with ten lives, rather than five.

Mystery Room
The Mystery Room (or ? Room) is perhaps the most well-developed secret in the Toy Box. It contains a total of eight different options for the player to choose from. Each must be unlocked by rescuing a captive from a castle in Original 1985 mode. Whenever a Toad (or Princess Peach, as the case may be) is rescued from a castle, they will show up in the Mystery Room.
 * World 1-4 Toad: Shows the player banners to print out on the Game Boy Printer.
 * World 2-4 Toad: Shows the player animations.
 * World 3-4 Toad: Shows the player banners to print out on the Game Boy Printer.
 * World 4-4 Toad: Shows the player animations.
 * World 5-4 Toad: Shows the player various graphics available for printing.
 * World 6-4 Toad: Shows the player a certain mode that allows him or her to create a sort of story.
 * World 7-4 Toad: Shows the player banners to print out on the Game Boy Printer.
 * Princess Peach: Shown an introduction screen editor where the player can replace the "Super Mario Bros: since 1985." title screen with different images, and add custom text.

Calendar
The Calendar was the only other feature found in the Toy Box to be accessible from the very start of the game. The calendar didn't do much. It was mainly just a way to keep track of the days. The player could mark certain days on the calendar if they were a specific event, (such as a birthday).

Yoshi Egg Finder
By finding at least one Yoshi Egg in Challenge Mode, the player will unlock this handy feature. The Yoshi Egg Finder is a sort of cheating device that helps the player find Yoshi Eggs in various levels of Challenge Mode. It operates like a roulette, flashing random levels at a high speed. When the player presses the A button, the screens will stop flipping. A brief snapshot will be shown of an area in a specified level as to where that level's Yoshi Egg can be found. This mode is entirely optional to use.

Trivia

 * In You vs. Boo the Black Boo (fastest boo) resembles the Black Boo from Super Mario Galaxy.
