I'm trying to boot review code of Gradius V (JAP) but the disc is damaged. I've backed up, reburned the disc and managed to load it, but all I get is a white PlayStation logo and sound, then it freezes. I burned it with Nero 220.127.116.11 onto a CD and am running it on a NTSC test PS2 - no restictions on retail or beta/R code. Any ideas why it isn't loading? Thanks.
