Topic on Talk:Medal of Honor: Allied Assault
Started making some edits, using autoexec.cfg mostly. There is a lot of mentions of unnamedsoldier.cfg, and newconfig.cfg. It seems to me that you can effectively have asd.cfg, not_a_file.cfg, or others. It's more about the '.cfg' extention.
Autoexec.cfg seems to be common, although possibly not a standard per say. Much easier to maintain than modifying the auto-generated unnamedsoldier.cfg, though.
Haven't found any definitive documentation about all the possible options, so best effort on some options.
