Before explaining this game, we should mention that the US version of Super Mario Bros. 2 is called Super Mario USA in Japan because they had a different Super Mario Bros. 2. (For more info, please read the SMB2 Madness special.) As a result, Japan's version of Super Mario All-Stars contains SMB, SMB2, SMB3, and Super Mario USA.
The BS Super Mario USA series is basically Super Mario Bros. 2 from Super Mario All-Stars with added features. Our favorite is the gold Mario statue. There are three statues in each level, and four in each x-3 level (you get one from beating the boss). Most of the time they are sitting out in the open, but sometimes they are hidden in Sub-Space (tricky!). Picking up a statue will give you a 1-Up and fill empty hearts in your life meter. To aid in your statue collecting, you can go back to play any stage that you have already beaten.
Another new feature is the "Today's Results" screen, accessed by pressing Select at the "stage select" screen. The results screen temporarily keeps track of all the Mushrooms, Coins, Cherries, and gold Mario statues that you've found in each level. Beat a stage, and the game will "X"-out the Birdo or boss you defeated. The red-colored stats show which level you were in last.
BS Super Mario USA marks the first instance of a point system used in a SMB2-style game. You can get a couple hundred or one thousand points from killing different types of enemies with vegetables, POW blocks, or other enemies. The stage select screen keeps track of your points, but points don't seem as important as collecting gold Mario statues...
It appears that the BS Super Mario USA episodes were broadcast a week at a time, starting on March 31, 1996.
