Metal Gear Solid (Game Boy Color)

Not a port of the PlayStation game, but an original 2D adventure for the Game Boy Color starring Solid Snake. Originally titled Metal Gear: Ghost Babel in Japan, Konami released it everywhere else as Metal Gear Solid because apparently western gamers wouldn't had made the connection if the words "Metal Gear" weren't followed by "Solid."

Title
The game is titled Metal Gear: Ghost Babel in Japan (a subtitle chosen because it shared the same initials as the Game Boy) and Metal Gear Solid in other regions (a title originally used by the PlayStation game to mark the series' transition from 2D to 3D). Presumably this was done for marketing reasons, as it was a common practice back in the day to release tie-in portable versions of popular computer and console games that shared the same title as their originals (such as the case with Perfect Dark and Tomb Raider) and the game also came into existence when Konami's European division commissioned a version of Metal Gear Solid for the Game Boy Color. Note that the American version is the only one that has a registered trademark.

IdeaSpy 2.5
IdeaSpy 2.5 is a text-only story featured in the Japanese and European versions that can be accessed during a second playthrough by calling frequency number 140.07 on the Codec. The frequency is given in red numbers during the end credits next to Shuyo Murata's name (the story's author). The frequency will play a different chapter on each stage (13 in all). This story is absent in the American version for unknown reasons.
