Special Settings#

Many people thought that the "Secret code" from Gran Turismo 5 Prologue that was discovered in 2010 originated from that title, but seeing as this is the earliest build of Gran Turismo on the PS3 that was publicly released, and with all other future builds branching from this one, that code actually originates as far back as this game here.

The input required is the same as the title above, except with the addition of holding down two other buttons. To access the Special Settings menu, go to the game's Options, scroll down to the Misc menu in the Miscellaneous category, and while holding down L1, L2, R1, and R2, input Down, Right, Right, Down, Right, Right, Down, Right, Right, Down, Right, Right, START and the Special Settings menu should now appear in the Miscellaneous category.

Function Overview#

Below is a list of all functions that the menu contains and a brief description on what they do. Given the available options, this menu was most likely intended for public kiosks and events.

• Unlock All - Exactly as it says on the tin, pressing the big shiny Execute button will unlock all cars available in the game.
• Save Full Lap Replay - Unsure about this setting's function, as saving a replay in-game will only save the best lap instead of the entire session anyway, but setting this option to Yes will not register the best lap time into the rankings when the player quits the race.
• Special Guest - Setting to Yes will allow you to edit the next option.
• Guest Name - A text entry box that only becomes available when the above option is set to Yes. Attempting to input anything will just bounce the cursor to the next option, pressing the start button in that box will cause the game to crash, requiring a console reboot.
• Time Limit - Sets the time limit of gameplay in 10-second increments, all the way up to 3600 seconds.
• System Language - Might have been used for the PAL territories version to change the language of the game, as only the game region's language is available to select from.

Unused Cars#

Subaru IMPREZA Sedan WRX STI spec C Type RA '05#

There exists name-only entries for the Subaru IMPREZA Sedan WRX STI spec C Type RA '05, a car which would later appear in Gran Turismo 5: Prologue. What's interesting to note is that there's an entry for a tuned variant, in which such a model never appeared in the aforementioned title.

There are other images relating to this car dating back to the first presentations of the title, however the official news from the GranTurismo website have been deleted over time and can only be found through the use of special sites such as Wayback Machine.

Nissan XANAVI NISMO Z '06#

An unused thumbnail image of the Nissan XANAVI NISMO Z '06 is still present in the game files. Footage exists of the car driven by an unknown construction, to date there are only remnants of the official pages where this car is specifically named.
Here you can find the article where it specifies where you could try this build.

Unused Tracks#

Inside the game's database (SpecDB, on the COURSE table), there is a track with the name of eiger_short_2006tgs, the Tokyo Game Show 2006 build version of the sole track in the game, Eiger Nordwand.

Unused Audio#

Jingles#

There are multiple short themes that, judging by the filenames, were supposed to play when the player finishes or completes a race, a feature which ended up becoming part of Gran Turismo 5 in which a multitude of themes would play depending on the position the player finished the race in. These four themes went unused in the game and remain within the data files.
