BS Super Mario USA Power Challenge is an ura- or gaiden-version of Super Mario Bros. 2 for the Satellaview system featuring graphical enhancements similar to its Super Mario All-Stars version. It was released in March-April 1996 by Nintendo in collaboration with the St.GIGA satellite radio station. As a 4-volume broadcast, each week bore a different subtitle. The names of the volumes were: 1) "I, Super Birdo"; 2) "Tryclyde's Secret Quicksand Surprise"; 3) "Fryguy on Pack Ice"; 4) "Wart's Trap, Look Out Mario Brothers". BS Super Mario USA Power Challenge was never released outside of Japan and as with all other Satellaview titles it has never been re-released as a stand-alone title. The game exists today solely in ROM-format and is traded online by Satellaview emulation enthusiasts.
