Red Faction stores the player name in the file players.cfg. This file stores the multiplayer name for the player in three locations in the first 263 bytes of the file. There is no visible checksum to this section of the file and can be modified freely. There is some extra data after the player name that cannot be modified and will mess up the config. However, we can make a default name that is 20 characters long and replace them as needed. If our name is shorter than 20 bytes, 0x00 is written to make up to 20 bytes. The game will trim these values for us and reconstruct the cfg file.
