SpecDB - Car Specification Database¶
Refer to the SpecDB concept documentation first.
Gran Turismo 4/5/PSP uses their own formats, which can be edited with the SpecDB Editor. It is also possible to convert said databases to SQLite for easier browsing.
Gran Turismo 6 uses SQLite which can be edited with any SQLite editor such as SQLiteStudio, it is required to decrypt it before viewing and editing it.
To decrypt it, use GTToolsSharp, decrypting and re-encrypting the SpecDB is done through one single command:
This command will decrypt or encrypt the SpecDB file using the specified key.
This key is normally found in
- The model code i.e
00080012is made up of 2 parts, the first 4 digits being the maker,
0008being Polyphony Digital, and the last 4 being the car's code.
- To link all part upgrades of a car in GT5, files named
PartsInfo.tbiare used. They are important as without them, going into car tuning settings will softlock due to missing parts. The SpecDB Editor will allow you to rebuild it.
Adding a Car to the game (from an existing model)¶
car/race/<model_file>model must exist or creating a car thumbnail, or going into a race will hard crash the game.
- Ensure that NumColors in
GENERIC_CARmatches the amount of linked rows in
VARIATIONor the Dealership will softlock.
- Ensure that
CHASSISis properly linked and has valid data or the garage/race screen will stay black upon loading.
- Ensure that
WHEELhas existing model files in the
- Ensure that every part in
DEFAULT_PARTSactually links to part row that exists.
- Ensure that the model code in
MODEL_INFOis correct or the dealership will not display the car and softlock upon exiting.
