The fats are out of production, but only the old fats have BC. The newer ones, released before the slim, don’t have BC.
There are three main types of fat PS3, the first NTSC ones with Emotion Engine & Graphic Synthesiser PS2 chips. Then there were NTSC & PAL models released with just the Graphic Synthesiser. Then finally ones with no PS2 chips at all.
If you have the original discs then you don’t need cobra & you can see for yourself what the compatibility is like.
From the compatibility list it doesn’t even seem worth the hassle, http://tortuga-cove.com/forums/viewtopic.php?f=57&t=530Tweet this!
