Yes those are the 3, (I no this cause there are only 3 in there)
If Your IGR are set to on it will cause some games to not work properly.
IGR and what do they do? From what I can tell it is used to reset your xbox using the controller, The default is Yes, While in a game hold buttons L-Trig+R-Trig+Start+Back all at the same time and your xbox will reboot. Why this causes some games not to run, I have no clue but it does.
I keep all my IGR's set to no, and really dont care about reseting my xbox from the controller, all i have to do is reach down.
