Version Deluxe!, lo que mas odio del SMB2J son los resortes! (AKA Muelles), el 90% de las veces, salto mal!. En segundo lugar el mugroso viento
Cambios en SNES
Many levels that had snow in the original Japanese Super Mario Bros. 2 do not have it in the Lost Levels edition, including 3-3, 7-1, 7-2, 7-3, 8-1, C-3, D-1, D-2, and D-3. Snow was mysteriously introduced into C-1. However, the snow is only an aesthetic difference.
The game can be saved at any time. Unlike the Super Mario Bros. on the same cartridge, the game remembers the exact level the player is on, and not just the world. This is because the game is much harder than the original.
Players only have to beat the game once to reach worlds A through D.
In the secret section of World 1-2 (where the player enters the pipe to World 4), the water pools were replaced by lava. However, the effects are the same: if Mario falls in, he loses one life. Similarly, the water in the first pit encountered in the level (after the Koopa Paratroopa) is removed in the SNES version.
In World 8, the Hammer Bros. perpetually charge at the player. On the SNES, this behavior was added to Worlds 7, 9, and A-D as well.
In the original game, Bowser only has hammers in Worlds 6-8. The SNES remake gives him hammers in Worlds 9 and A-D, as well. Strangely enough, these Bowsers lose their ability to breathe fire.
The Bowser Impostors in Worlds A-C now have new true forms (a red Koopa Troopa, a Cheep Cheep, and a Bullet Bill, respectively), and Bowser's death animation in World D is corrected.
The castle walls of World 9-3 (whose background is sky blue instead of black) are now recolored brown instead of gray like in the original (and in the ending cutscene).
Cambios en Deluxe
Super Mario Bros. Deluxe was marketed as a Game Boy Color enhancement of Super Mario Bros., but if a player gets on the high score table with 300,000 points or more, a Luigi head appears on the main menu. Players may select the Luigi head to play The Lost Levels under the name of Super Mario Bros.: For Super Players.
In this game, as in the Super Mario All-Stars version, the player may save and resume at any level. However, most changes removed features from the original release. This remake removes the graphical changes from The Lost Levels and thus looks just like Super Mario Bros. Additionally, Luigi's higher jump and lower traction are removed, as is wind. As a result of the lack of wind, some levels are modified to make the jumps possible. Another change is the removal of Worlds 9 and A-D, although they are all at least somewhat present within the game's coding.
