The New Way to Practice The New Super Mario Bros. Games
The New Super Mario Bros. practice roms are designed to make practicing each game easier for everyone. These will improve already existing practice roms, or make practice much more efficient for games that don't already have it. This means that anyone, veteran or newbie, can learn, practice, and test strategies they want to more efficiently than ever before.
