RCO Editor question

Anybody know the rco file where you can find where it asks if you want to end the game when you press the home button?
Its kinda pointless to edit XMB text when CXMB themes usually override the changes you make, but I do have a use for editing this text. I just dont know what file it would be in and theres a buttload of files in the resource folder to sort thru. Just hopin someone else already knows and can save me a bunch of legwork
As always , will rep+ and donate for good help
