Im not sure what the Globe is but as for physical mods such as leds, paint etc they cannot scan for. The only thing they can scan for is if you are playing with a flashed drive and you are using burnt or modified games. Someone please correct me if im wrong.
From what i understand they cannot detect different firmware. They would have to dump a copy of the firmware to tell that you had a different kind of firmware. They can detect how the firmware reads the disks.
I'm not 100% sure how globe 360 works. I seems to me like a separate firmware chip that over rides the original. I would say that it wouldn't be detected but i'm not 100% sure.
