Super Mario World 2: Yoshi's Island (sometimes referred to simply as Yoshi's Island) is a 2D platform game for the Super Nintendo, developed by Nintendo EAD. The game is the prequel to Super Mario World and chronologically the first in the Mario franchise. The game is notable for introducing a time-based health system rather than hit points, an anomaly to what many platform games typically did in this game's time period. Rather than relying on powerful pre-rendered graphics as its contemporary, Donkey Kong Country did, Super Mario World 2: Yoshi's Island employs a very distinct, stylized arts and crafts style to stand on its own. The game makes use of the Super FX2 graphics chip (one of only four commercially-released SNES games to do so), which allows for larger, more detailed sprites and more advanced effects that emulate 3D space.
Hacking Tools
Standard
Golden Egg
