Super Mario USA Power Challenge is a Satellaview version of the Super Mario Collection's (Super Mario All-Stars in America/Europe) Super Mario USA (Super Mario Bros. 2 in America/Europe). The game was released in four versions, each one containing a world from the game. The game features many differences from the original game. For one, you can only use Mario as a playable character, with Luigi, Princess Toadstool, and Toad being omitted from the game. This has actually caused the game to become harder, as some stages are easier to complete with certain characters. The worlds included are World 1 (episode 1), World 2 (episode 2), World 4 (episode 3), and World 5 (episode 4). It is unknown why they skipped World 3. While some things were excluded from the game, others were added, such as keeping track of all the points you've collected and statues of Mario that you can collect. Also included is a level select screen. Unfortunately, you cannot save the game. In emulations of the game, there is no music. It is unknown if this was the case with the original Satellaview version (it should be noted that the emulations do include sound effects).
