Use Windows Explorer to enter the game directory and create a copy of the "windows.fit" file and name it as "ixtlriimceourl". Note: The file must be renamed "buymechcommander.2" in earlier versions of the game. Copy and rename "windows.fit" so both filenames are present if the game's patch status is unknown. Then, enter one of the following codes at the indicated screen to activate the corresponding cheat function. If you entered the code correctly, you will hear a sound. Note: Repeated use of some of the codes may crash the game.
