This title is a Mod for the Nintendo DS, released in 2012, that faithfully recreates all levels from the original *Super Mario Bros.* and *The Lost Levels* using the engine and style of *New Super Mario Bros.*. Gameplay involves classic 2D platforming, enhanced by custom level expansions hiding Star Coins and updated graphics that blend retro blueprints with the modern aesthetic. Challenge is increased via modified Bowser Jr. fights, appealing to fans seeking classic level design within a contemporary framework.
The central focus of this modification is the faithful recreation of nearly every stage from both *Super Mario Bros.* and *The Lost Levels*. This includes the entirety of the original game's worlds, as well as the notoriously difficult bonus worlds found in the sequel, specifically Worlds 9, A, B, C, and D. While the original retro level blueprints are preserved, the presentation is updated to align with the aesthetic of the *New Super Mario Bros.* engine.
Gameplay retains the established platforming physics of the base game, but the level construction has been enhanced. A notable addition involves level expansions, where custom areas have been integrated into most stages. These new sections often serve as locations where hidden Star Coins—a collectible mechanic from the base game—are strategically placed, encouraging thorough exploration beyond the original paths.
Visually, the modification implements new graphics, including updated tilesets, backdrops for both screens of the Nintendo DS, and revised world map textures. Even the original retro graphics have been adjusted to fit seamlessly into the visual style of the *New Super Mario Bros.* presentation, ensuring a cohesive atmosphere while retaining the structural integrity of the classic stages.
While the original themes and structure of the classic levels are maintained, the difficulty has been adjusted in specific areas. A key change involves the boss encounters, as the Bowser Jr. fights have been modified to introduce greater challenge compared to their original iterations in the base game.
This release is comprehensive in terms of classic content integration:
There are no officially listed DLCs or separate expansions available for this modification.
