Super Mario Advance

Super Mario Advance (Japanese: スーパーマリオアドバンス Sūpā Mario Adobansu) is the port remake of Super Mario Bros. 2 developed by Nintendo Research & Development 2 as a launch title for the handheld Game Boy Advance, released in Japan in March 2001 and in North America and Europe in June of the same year. It is based on the Super Mario All-Stars remake for the SNES, and also contains a remake of the original Mario Bros. game. Advance includes many new features, gameplay mechanic changes, graphical and audio enhancements, and stylistic and aesthetic alterations from the All-Stars edition, with the most significant changes being the addition of the enemy Robirdo, a robotic Birdo, replacing Mouser as the boss of World 3; the addition of the "Yoshi Challenge", in which players may revisit stages to search for Yoshi Eggs; a new point-scoring system; multiple hit combos; enlarged sprites; and digital voice acting.

The game was re-released on the Wii U's Virtual Console in Japan on July 16, 2014, in North America on November 6 of the same year, and in Europe and Australia in March 2016.

Changes to Super Mario Bros. 2 from the All-Stars edition
The boss order is slightly altered: a new enemy named Robirdo, a robotic Birdo, acts as the new boss of World 3; and the second Mouser is moved to World 6, where he replaces Tryclyde. After the game is beaten, a "Yoshi Challenge" mode is added; the player may revisit the levels to search for two Yoshi Eggs per stage, hidden in Subspace where they replace two of the Super Mushrooms, and is allowed to select any level to play regardless of whether or not they played them before beating the final boss. An all-new point-scoring system is introduced, similar to that used in the BS Super Mario USA Power Challenge; players get more points for making one thrown object hit lots of enemies, and are awarded an extra life if they hit enough foes. Two new items are introduced in Advance: the Roulette, which gives the player either a heart, a bomb, or a Super Star after being thrown; and the "Spark Chaser," located inside vases, which clears Sparks on the walls, ground, and ceiling. Five red Ace Coins are added to each level, which reward an extra life if all are collected in a single play. The level intro screen is now accompanied by a "map screen" which shows what levels the player has cleared; when all five Ace Coins have been collected in a certain level, a star is added to the corresponding panel.

The placement of certain 1-Up Mushrooms is changed, and there are also mushrooms sitting on the surface; these ones are usually contained within bubbles, which the player can pop by hitting it three times. Hearts (here resized) appear much more frequently than in the original; they appear whenever three or more objects are involved in a collision, and appear as special radishes that can be pulled up from the ground. Other gameplay changes in Advance include the default health-meter level being altered so that players start each new life in Small form; the addition of a "Try Again" feature that allows the player to restart difficult levels from the beginning; changes in enemies' behavior so that they do not respawn unless the player leaves and reenters the area; the addition of large carrots to the first and third levels, which spring from under hills to catapult the player to higher places; the ribbons of red and green Birdos being removable; and players being allowed to bet more than one coin per spin in the Bonus Chance game.

The game also features "giant" variants of vegetables, enemies, and POW Blocks, with enlarged sprites. The giant vegetables have larger areas of reach; the giant enemies yield hearts when picked up; and the giant POW Blocks bounce around and shake enemies off the screen four times as opposed to just once. Red Shells are enlarged as well, and are now capable of bouncing off walls, yielding hearts, and hurting the player. The areas within vases are completely revamped, gaining a new background and an original music cue; some vases also incorporate Ferris wheel platforms with Shy Guys riding them. The developers reduced the display resolution to fit better on the GBA screen, and brightened most of the original color palettes to combat the handheld's lack of a backlight; in the process, Subspace lost its original dark-blue tint, the Mario brothers' overalls were changed to the standard blue, and Toad's vest was recolored purple like in his 1980s artworks. Other graphical additions include a "flash" effect that appears when the player touches a Spark; new sprites that actually show the player characters going through upon entering a door; and an enlarged sprite for the Phantos that appears in full size when they exit the screen upon the player's throwing the key or losing a life.

The original forms of the enemies Fryguy and Clawgrip are seen before the heroes battle them; four giant bubbles transform them before their fights. Digital voice acting is added for the four playable characters, who are given voice samples for such situations as being chosen, picking up items like Mushrooms or Crystal Balls, gaining an extra life, winning a level, and losing a life; and the bosses, who are given lines of dialogue for when they begin their respective battles and when they are defeated. A chime is added to announce Super Stars, and Phantos now make the same noises as the larger Phanto in the background of the key rooms as they move around the screen. Textual changes include Princess Peach reverting to her original Japanese name, correction of misspellings and the Ostro/Birdo mix-up in the international version of the credits, and the player who was used the most times being called the "MVP" instead of the "Contributor" in the ending.

Mario Bros. remake
The game features a Mario Bros. remake that carries over into the other Advance games and the RPG Mario & Luigi: Superstar Saga. The remake features a "Classic Mode" based on the original game's co-op mode, and a "Battle Mode" similar to that used in the All-Stars remake of Super Mario Bros. 3. Changes to the original game come in the form of enhanced graphics, the addition of music where it was originally absent, an extra POW Block in every stage, the addition of the Power Squat Jump, and the replacement of Shellcreepers with Spinies.

Development
Super Mario Advance was developed due to the success of Super Mario Bros. Deluxe for the Game Boy Color in America in late 1999. Despite the use of most graphical and audio assets from the All-Stars version, the game was coded from scratch; new sprites and audio cues were created because their existing counterparts were "not good enough". The development team purposefully decided to add "large" versions of enemies and increase the number of enemies on-screen as a means of highlighting the Game Boy Advance's processing power. The Mario Bros. remake was initially a separate project designed to experiment with the Game Boy Advance's link cable feature, but it was eventually decided to include it as an extra.

The main staff for this game includes directors Satoru Iwata and Toshiaki Suzuki, producer Masayuki Uemura, and assistant director Hiroaki Sakagami.

Reception
Super Mario Advance received generally positive reviews, garnering an aggregate score of 84% on Metacritic. When GameSpot reviewed the game, it thought that Super Mario Bros. 3 or Super Mario World would have been a better choice for a launch game considering their respective popularity; both titles were eventually also remade as part of the Super Mario Advance series. Conversely, IGN praised the choice, calling it "one of the most polished and creative platformers of the era".

Glitches

 * When playing World 2-2, World 3-1, or World 6-3 as Luigi, the player can pick up a Spark Chaser out of its vase, hitting a Spark at the top and trying to get to one side or the other in the process; once the player leaves the vase, the Spark Chaser becomes a Yoshi Egg, with no change in behavior.
 * In World 2-3, if the player does a Power Squat Jump to the ceiling in the digging area with the Key in hand, their character can get stuck in the wall.
 * In Fryguy's boss fight area, if the player slides underneath one of the Flying Mushroom Blocks and releases the down button the character's body will be stuck inside the block; the player can get out of it by sliding again.
 * In World 5-1, if the player jumps on the rightmost log, jumps on top of the wall to the right, picks up the first mushroom block and throws it right before landing, the block will float in mid-air.
