Just editing the racelogo.tga file will not work, there are layers involved with this file.  they are using a hidden feature in the background called alpha Channels.  I have looked at this but im not able to remove the highlighted sections under the Alpha channel.  im not experianced enough with this part.  does anyone know how to remove this or edit it t owork?  I do know that if you mess up the Alpha it will not show the icons in the game they will be  blanked out with the player color.
