Some rad dude has created a Java version of Mario Bros. It�s a funny hodge-podge version mixing all of the versions up until Super Mario. It�s got the overhead menu layout of Super Mario 3 and a lot of the graphics from Super Mario with a bit of 1 and 2 thrown in for good measure.
Use the arrow keys to move mario around.
Press A to run faster and to pick up shells.
Press S to jump.
