gta3.set

Jump to: navigation, search

The gta3.set file is a binary file that stores the game's configuration settings for GTA III. It is located in the User Files directory. The game automatically generates this file with default settings if it is missing. Each time a setting has been changed within the game menu, the file changes immediately.

Format

Oddly, any settings that begins with a value of 0x0A will be padded with the prefix 0x0D. This means that the settings file can vary in size. For example, if a screen resolution is 0x0A, then the game will prefix and save the value as 0x0D0A. Even with floating-point values which are in little-endian order, if it starts with 0x0A it will still be prefixed, e.g. 0x0AD7233B (0.0025 in little-endian order) will be prefixed and saved as 0x0D0AD7233B.
