Super Mario World Localization Prototype Discovered
The website Forest Of Illusion is dedicated to the preservation of video game prototypes, and makes them available for the public. A lot of surprising finds have been posted to that site over the years, but they saved one of the biggest Bob-ombs for Christmas: an in-progress localization prototype of Super Mario World, dated October of 1990 — ten months before the game would go on sale in the US and Europe!
