Oh, I prolly shoulda mentioned that they also might ban your PS2 from online (or atleast from EQOA). Which really only means that the bios you're using will be banned. Since you're also prolly not using a bios from your PS2 (which is illegal if you aren't, pirating software) then that bios might end up banned, disallowing your EQOA access. However, if you are using your PS2's bios and not your game's ID then your real PS2 has a chance of getting banned.
I'm just throwing this info in. Not at all trying to imply that it WILL happen, only that it MAY. Honestly, I doubt it will, but that bascially how it worked for Socom I, II, III & III:CA.
However, C9 ("Code 9") and other methods of cheating on Socom will not work on EQOA because the server is where all the info is, and it doesn't trust the PS2 client enough to change any server side data based on it. Such as changing your char's name will only be cosmetic -- it will only change it on your screen. The server and other players will still see your original name.
The game is pretty laggy on a 2.8 GHZ dual core AMD processor. Unplayably so as a tank (and possibly healer). And all cases where fast action will keep you alive. Not sure how much help a better graphics card will be though, as this lag was with an integrated video card.
