Gran Turismo for the PlayStation Portable (not to be confused with the original) is Polyphony Digital's attempt at bringing the series to a portable device. Originally announced as Gran Turismo 4 Mobile at E3 2004, and having a vaporware status for around 4-5 years, it wound up being released in October 2009, with the absence of a real career mode, and began the terrible tradition of having regional duplicates of many cars - most of them because they were on previous games' discs on every region.

Sub-Pages

Cars A lot of car related stuff missing from the game.

Tracks Many tracks planned into the game went unused.

Unused Cameras

Normally, the game has 4 different cameras: bumper (value 0), cockpit (value 26), roof (value 6), chase (value 1). Starting from these values, it is possible to access the numerous unused cameras; moreover, most of them have their own name. If the camera itself is missing, the game will show up a superzoomed internal cam.

Revisional Differences

Several early Japanese copies came with a different opening movie, including Moon Over the Castle as the opening movie's theme song.

"gt5m" Strings

Although the game is largely based on assets from Gran Turismo 4 (the game was originally planned as Gran Turismo 4 Mobile), it is internally referred as Gran Turismo 5 Mobile. Evidence of this can be found in an early video, where the game displays course_gt5m_spec in the bottom part of the track selection screen. Moreover, using a cheat application (such as CWCheat on real hardware), it's possible to see that within the GT.VOL file, almost all folders use the gt5m name.

It is interesting to note that the game is almost identical to Gran Turismo 5: this is not supported only by many mentions of tracks and cars from that game, but also from the internal structure of the game itself; this confirms their parallel development even more. Additionally, a teaser for GT5 is included in the game's ending sequence.
