I have checked quite a few version guides... which all seem to be 95% the same or more, heh. Anyways I'm trying to figure out what version my PS2 is obviously, but I'm getting tons of mixed messages. It says if I have a certain screw in my expansion bay then I have a V5/V6, if I don't it's a 4. Well I don't, so it's a 4 right?(maybe) Then comes contradiction. It says if my model # is 30001 R then I must have a v5/v6... but I don't have the screw they're talking about, so it's supposed to be a v4. Then comes the electric shock warning on the bottom. I've seen many sites opinions, most of them say If I have it(which I do), that it's a v4. But I've come across a few sites that say both v4 and v5's have the warning label. So basically I have Model #30001 R which is supposed to be a v5/v6 model #, but I don't have the screw in my bay so it should be a v4. And then I DO have the electric shock label. Sorry to make this so drawn out I'm just trying to work some things out in my head as I go. Thanks in advance!
