Thank you very much my friend. Can you say me if Goldstar DVD-R are good media or not?
The modchip inmy PS2 is named Titan, this is the name that the seller told me, but I didn't find anything on Internet: is it the right name or is it a nick for another name?
If Titan is right, do i need a boot before? I tried with a copy made with Istant Copy and it doesn't work: after 3 reboot it show me something, but it stop after Activision logo (the game is Tenchu Wrath of Haven - a really beautiful game).

Thank you for your help and your patient. I hope you can answer me soon.
Thank you.
Akira
