Metal Gear (NES)/Changes from the original

There are two different versions of this game. The original was developed for the MSX2 home computer by Hideo Kojima, and the NES version was programmed by a separate team at Konami. Other versions, such as the Commodore 64 and MS-DOS versions of the game, are based entirely upon the NES conversion. Of the two versions of the game, the NES version is far more common and popular among North American players. However, this version contains a number of changes to the game that were made without consultation from Kojima, who has stated his dissatisfaction with a number of details of the conversion. In addition to having different soundtracks from one another, and a slightly better look on the MSX2 due to a higher resolution and palette count, many aspects of the game were changed.
