Ahem NO ****ING WAY. I have done a lot of research on the HDD. And alot of testing of stuff. To get a game to play from HDD you would have to re-write the entire game. To get online first you need to have both the same region ps2 as the game region and secondly the DNAS "patch" is a bit buggy. Also look for sony to patch the servers. Further the HDD patches the bios and disables all modchips. Lets put it this way, you're asking for the impossible if you want this buy an xbox.
