"..A swap trick has been discovered for playing import / backup Playstation games on Playstation 2. The trick is discovered by people in Japan, which only works for PS games (not PS2). The swap trick involves opening the PS2 case, remove the disc spindle lock from the DVD drive, and perform the swap trick during the booting sequences. However, because the swap trick involves disassembling the PS2, it is very risky and could cause permanent damage to your console, and you should only treat this as a reference, we are not responsible for any damages you made to your PS2.."
