By the way, the XOSL technique has the added advantage of affixing the cheat codes to the system that needs them, not to the CD or DVD. That way you can use the same CD in several systems that might need different cheat codes, or carry it elsewhere, and it will behave like a normal Knoppix CD (which it is). You also can download new versions of Knoppix and not have to edit anything to make the work automatically with the same codes (although on occasion a new version does either need different codes or no longer needs codes it perviously did, but this is extremely easy to change in XOSL, whithout even manually editing a config file).
