Super Mario World Worlds & Levels
Dinosaur Land’s nine areas, from Yoshi’s Island to the Special Zone: 76 levels (counting Yoshi’s House and the Top Secret Area) with 24 secret exits, the Koopaling in each castle, and the enemies placed in every level, read from the game’s level data. The maps are drawn from the overworld’s own tiles.

The main map: Donut Plains on the left, the entrance to the Vanilla Dome at the top, the Twin Bridges top right, the Forest of Illusion on the right and Chocolate Island at the bottom. Yoshi’s Island, the Vanilla Dome, the Forest of Illusion, the Valley of Bowser, the Star World and the Special Zone are separate submaps.
Yoshi’s Island

The starting island. Mario, Luigi and Princess Toadstool arrive in Dinosaur Land on holiday; when Mario reaches Yoshi’s House, Yoshi has gone to rescue his friends from Bowser. The first Yoshi egg hatches in Yoshi’s Island 2.

Pictures drawn from the Super Mario World (SNES) game data: sprites are assembled from their tiles the way the game draws them, in the palette of a level they appear in; blocks, coins and berries are built from their 16×16 level-tile definitions with the animated tiles in place; maps show the overworld’s terrain layer (the level tiles and paths on its other layer are not in the asset export). Animation timing is approximate. The enemies column lists the regular enemies in the level’s sprite data, its main area and sublevels together; power-ups, platforms and bosses are left out.
