This is a Hong Kong bootleg hack that is supposed to be Super Mario World, but plays more like Super Mario 2 or The Lost Levels. It is not authorized nor sanctioned by Nintendo.

A rushed hack, and it shows. Game control is off, lots of little details from the REAL game is missing, and what's that SUPER MARIO BROS sign doing in there as a second title screen? The whole thing winds up looking and feeling like a port of the public domain game Mario VGA. Nintendo is not happy about the existence of this unlicensed port, and it's easy to understand why.
