You modded your PS2 and still paid for bootleg games? The procedure for getting PS2 games off the net is as easy as sticking a Hot Pocket in the microwave, hitting 2:30, and watching it cook. You got ripped off buddy.
Anyhoos, I have a modded PS2. I'm pretty conservative with buying most of my U.S. games, and primarily used it to acquire Japanese torrents of games I would never understand anyways, like NamcoXCapcom. I just couldn't justify buying these games as imports as I would only mess around with them casually. I also got some rare games off torrents if the used price was rediculous and if the original was off the market, like Disgaea, Marvel vs. Capcom 2 and Shin Megami Tensei: Nocturne.
