(adsbygoogle = window.adsbygoogle || []).push({}); Okay, I want to play PS2 Iso files on my 3.55 PS3 running on Kmeaw, I don't have the money to buy CobraUSB, can I play them without it?

i think so , isn't cobra a method of downgrading to 3.55 , but seeing as you have 3.55 already you won't need it.
