Super Mario All-Stars + Super Mario World (1994)

Put quite simply, this is the amalgamation of the previously released Super Mario All-Stars compilation with Super Mario World added. While games already in the All-Stars bundle have major graphical and audio improvements, the only change made to Super Mario World is a slight tweak of Luigi's graphic sprites, making him slightly thinner and taller (rather than being the same height and stature of Mario) which does not affect gameplay.
