I just got a DVD burner a week ago, I want to backup the PS2 DVD disc. But I burned it in the 4X speed with the DVD-R disc, while i used the swap magic 2.0 DVD disc to boot the game but it cant boot, it shows that the red(cant not boot), then I use the Swap magic 2.0 CD boot.. then change the GT3 original disc to have a bigger TOC to boot the disc. it can boot very well.. then I found that the disc my cousin burn for me which can boot with the SMD DVD is different from my disc.. is there any problem about my PS2 or any problem with my DVD-R disces or my step of burning way is wrong... I already burned the disc with Alcohol 120%, NERO, and DVD Decrypter,but they still cant boot with the Swap magic DVD 2.0 disc!!! can someone figure it out and help me out???? ps: I already changed the new lens for my PS2..my ps2 version is 300001F, is that my PS2 is too old to play the backup disc?!!!!
