Maybe I'm just not the right one to help you and I apologize, but I still don't know if you're on 4.82 official firmware or 4.82 custom firmware. I have a PS3 Slim that was downgraded to 3.55 and I'm on 4.82 custom firmware. I can do pretty much everything like play PS3, PS2, PS1 games, with cobra and multiman. I am unfamilar with any other hack I just know there's a huge difference in how they work. If you are on custom firmware you can just download and install rebug toolbox pkg and turn on cobra. If you don't do this you'll continue to have problems. But if you have some other hack I don't know how to help.
