Don't mean to cut in. But this is TheUnkn0wn's and hunter128's method. Me and my mate brendanj9554 just came across it, so they deserve most credit, plus brendan found a lot more than me since i went through a few ps3's installing the infectus.
And that idea sounds pretty cool, but i don't reckon it could work now, but we never know what this method has unlocked, so as PS3 said, post here if you come across anything, it will be awesome to see this get further than "game modding"
That's why he posted last year about installing infectus, and the only replies he got, were it was patched.
But i guess thats all we could get for answers since until now, nobody knew it went further.
