E.T. the Extra-Terrestrial is infamous to gamers. This Atari 2600 atrocity was programmed in five short weeks to prepare for the holiday shopping season and was unanimously hated upon release. Spurned families returned the games, leading to one of gaming's juiciest legends. Supposedly, many of the carts were buried in a landfill due to excess, unsellable stock.
One fan who goes by the name "recompile" enjoys E.T. They enjoy the game so much that they studied the game and its code and have fixed it. Well, at least, as much so as is possible without actually changing entire aspects of the game to make it fun. There were definitely real bugs in the game though which have been remedied.
Changes to the game include collision detection for the holes in the ground. Originally, having any piece of E.T. overlap with a hole would result in the alien falling in. This has been changed to make it react the way we expect, where E.T.'s feet must be over the hole to fall down. His color was also changed to reflect the film's actual skin tone. An extra mode was even added in for fans to experiment with. These updates and more are detailed in depth on Neocomputer.
Will E.T. the Extra-Terrestrial for Atari 2600 ever be able to fade into obscurity?
