Unused Cameras#

Normally, the game has 4 different cameras: bumper (value 0), cockpit (value 26), roof (value 6) and chase (value 1). Starting from these values, it is possible to access a number of 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, which included "Moon Over the Castle" as the theme song.

"gt5m" Strings#

To do: Find the early video in question, and compare further the game's VOL format (and what's inside it, such as how tracks are internally named) to that of GT5's.

Although the game is largely based on assets from Gran Turismo 4 (as it was originally planned as a mobile version of that game), it is internally referred as "gt5m", which (likely) stands for Gran Turismo 5 Mobile. Evidence of this can be found in an early video, where the game displays the string course_gt5m_spec in the bottom part of the track selection screen. Additionally, the game was developed in tandem with Gran Turismo 5, as many of cars and tracks that ended up appearing there (or had appeared in Gran Turismo 5 Prologue) are also listed in the PSP game's files, and the similarity of the internal structure between GT5 and GTPSP. Additionally, a teaser for GT5 is included in the game's ending sequence.

Additionally, several files and folders in the game's GT.VOL file use the "gt5m" codename, such as:

advertise/gt5m-us/XX/
image/piece_gt5m/
piece_gt5m/
projects/gt5m/
scripts/gt5m/
textdata/gt5m/

In addition to that, "gt5m" strings can also be found near VersionApplication strings in the console's RAM.
