I'm pretty sure this game never saw a release in any of the Americas. The US is part of the North America region. And for instance, I'm pretty sure the SNES was released in Canada, which is not part of the US.
This is a complete hack of Super Mario Bros 3, featuring 4 new worlds and 1 secret world! All worlds are filled with new levels, new graphics, new asm mods and more!
Just play it and you’ll discover the new things by yourself :)
