As someone who has used undocumented methods on many consoles and ALWAYS been caught by QA and told to remove them I'd love to know how they got away with this.

As someone who has used undocumented methods on many consoles and ALWAYS been caught by QA and told to remove them I'd love to know how they got away with this. Even on the PS1 where I used an undocumented graphics command to get a 'free' screen clear (nothing dodgy and we learned about it by watching Tekken in the PA) I got told to remove it.
