It is possible with a modded PS2. But I don't think you really need that. (it's a lot of hassle)Most easy is to get swap magic.http://www.swapmagic3.com/You will need the ntsc version of swap magic. No clue where to buy it. But google knows or if you already have a network adapter, then hdd loader for ps2 is a good option too. But you'll need a few things more. (psx memorycard and psx game)
