config.opt

On startup the game will look for the file %appdata%/FUEL/FUEL/config.opt with the format described below. If this file exists, then the values in the struct will take precedence over the values in the registry. It is important to note that this file is not created by the game and does not come with the game, but it can be created manually. The config.opt file from Up matches this format and can be used in FUEL. The version number from the config.opt file in Up matches the version number found in the registry for FUEL.
