Super Mario World is a side-scrolling platform game developed and published by Nintendo for the Super Nintendo in 1990. When Mario goes on vacation, Princess Peach gets kidnapped and Mario must go through Dinosaur Land in order to rescue her from the evil Bowser.

A "Lost Levels" styled hack in that there's very little in the way of new enemies and features, but there is a steeper learning curve and a ton of secrets to find within those levels. Don't worry if difficulty hacks scare you though, many of the early levels are still easy and there is a sincere attempt at level design and variety.

This hack improves on the original version in the following ways:

1. All Koopa Kids, Bowser, and Reznor are more difficult, keeping with the tone of the hack.

2. Lag is considerably reduced.

3. Sprite memory is improved in a few stages

4. Various bugs, some minor, some major, have been either eliminated or minimized.

5. A few minor level edits to fix bugs, such as removing Yoshi in Forest of Illusion 3 and removing the final Pokey in Chocolate Island 5, and one major level edit with Yoshi's Island 3 now featuring a faster scroll.

The hack is about 95% the same, but the changes generally make things more difficult. Unlike the original, it is not a pure vanilla hack as it takes advantage of a few patches and hex edits to tweak a few things here and there. However, it still resembles a vanilla hack in all essential ways, and those few changes ultimately allow it to play much better than the original version.
