Hi guys,

I've tried backing up my GT4 game with dvd decrypter & nero to a double layer disc & nothing. The copies I've made with both programs only boot up " Sony is a registered trademark....." & that's it. It stays black & the game doesn't finish booting up. I have a Ps2 v9 modded with a DMS 3. I've downloaded & burnt copies to a DL-R DVD before with no problems, but I cant back up my Gran Turismo 4 NTSC game. It's a classic 4 me I don't wont to scratch & ruin the original. Can somebody help me or point me into the right direction. I don't want to flatten it or anything like that. I just want to make a 1:1 copy. Thanks guys.

Try bunt it to DVD+R

I've tried DL DVD+R & DL DVD-R with same outcome. Is there maybe a program I need to use to make a better iso if so, with what settings?

Do you change booktype from DVD+R DL to DVD-ROM??
