When I was getting loaded into a game on Resistance just about 5 mins ago, I pressed the PS Button and instead of the menu coming up, the screen froze and the coding below came up. Not really sure what it is, but I am guessing it is telling the PS3 what to do to get into the XMB, hope this helps, I got a video of it also if I can get it off of my dads phone. The * is something I dont know but will get later.
Probably just some coding that was loading and stuff, but if you think we could use this. It is definatly a glitch in the PS3.
UPDATE: pressed it a little soon and I noticed that a couple of the codes changed, I hope this helps any.
Here is a video of it in action
