Metal Gear (MSX2)

The humble beginnings of Konami's popular stealth action series, Metal Gear is an MSX2 game where players control a covert operative with a phallic-sounding codename who must infiltrate an enemy base guarded by soldiers with no peripheral vision.

Regional Differences
Unlike most of their previous MSX releases, instead of including a region detecting code in Metal Gear, Konami produced two versions of the ROM cartridge: a domestic Japanese release and an English version for the European market. For some reason, presumably done to quicken the localization process, the English version only has 86 of the 155 radio calls from the Japanese version translated - the rest were eliminated. The deleted calls consisted of item descriptions by Big Boss and calls answered by Diane's brother Steve in areas where Diane is unavailable to help Snake. These calls were rather trivial in nature compared to what was kept, as they were only added to give the characters more personality rather than to help the player actually proceed through the game.

A fan-translated patch of the Japanese ROM, titled "Metal Gear Remix", was released in 2005 that restores all of these deleted calls. Additionally, Konami's official re-release of the game included in Metal Gear Solid 3: Subsistence features a new translation that retains all the radio calls as well.
