i'm not sure about the 80gb consoles being bc for ps2 as im pretty sure they werent released in my country. if you can find out the model number eg cecha01 i can tell you then. but as far as i know cfw doesnt affect the bc so if it came with bc originally it will be ok.
just be careful buying a fat ps3 as the release consoles are poorly designed and have a YLOD fault. make sure the security sticker is still attached where you pull the console apart to ensure it hasnt been repaired already.
Alright cool. Thanks, the seller has a return policy so I will check it as soon as it gets here. I am guessing there is a tutorial on opening a ps3 so I should be able to do that and check what you said.
I am not too hard-set on it being ps2 backwards compatible I was just curious about that part. I mainly just wanted to make sure I could do what I wanted to do to it which is the cfw before I shelled out the money for it.
if it is bc I will let everyone know if there isn't already a topic for it once I test it.
