Mainly PS3 structures.
Represents a car structure and all its parts/settings. Mainly used when serializing to save.
Should support GT5/GT6 though I wouldn't be surprised if it could break somehow. Tried to follow versioning from the game code as much as possible.
MGameParameter aka event files in PS3 GTs have a XML and binary version. The binary version actually gets really close to the one that stays in memory that the game uses. It's also version checked.
GTEventGenerator attempted to create them after painfully reversing the bit stream (which I got quite close!), reversing default values aswell, but it may still cause crashes in some cases so some more work is needed.
