Super Mario World (partially found early build of Super Nintendo platformer; 1989)
Super Mario World is a 2D platforming game that was directed by Takashi Tezuka, produced by Shigeru Miyamoto, and released for the Super Famicom in Japan on November 21st, 1990, and the Super Nintendo in North America in 1991 to universal acclaim selling over 20 million copies worldwide.
Development began in early 1987, making it one of the first games developed for the Super Famicom. The team of 16 people started off by porting the Nintendo Entertainment System game Super Mario Bros. 3 to the Super Famicom so they could experiment with the new hardware. Even though this version of SMB3 was just a port, it did feature improved 16-bit sprites with much more vivid looking colours. The team then used this port as a base foundation for all of Super Mario World.
The 1989 Build
The "1989 build" was shown off in a Japanese magazine in 1990 and showed off many differences to the final game. some of these differences are that the build only had a total of 16 levels, a completely different overworld world map and a completely different small Mario sprite. Furthermore, the build also has many similarities with Super Mario Bros. 3, such as some of the sprites for objects and enemies. But, the most notable similarity is that the "Raccoon Leaf" powerup from Super Mario Bros. 3 appeared in the build and is fully functional.
Although the "1989 build" hasn't been seen since 1990, some photos of the build have appeared in Japanese magazines and also some of the builds sprites appearing unused in the rom of the SNES Burn-In Test Cart. In July 2020, a huge Gigaleak revealed the source codes of many early Nintendo games, and Super Mario World was one of them. While this leak didn't include the 1989 build, it included many of its assets, like beta enemy sprites. However, the chances of the full "1989 build" ever seeing the light of day are very slim due to the fact that Nintendo has a tendency not to leak or release unfinished builds of their games.
