Okay, so I found a disc only copy of Panzer Dragoon II Zwei at the flea market today, it was a bit scratched but I got it for $4 and took a chance. My luck with scratched Sega discs being what it is, of course the game doesn't work when I get it home to test it (seriously, I've picked up 2 or 3 loose Dreamcast and Saturn discs in the last few months in what I would conciser 'fair' condition. And none of them have worked. Discs in similar condition on the PS1 and PS2 work like champs. I really don't get it. Anyway....)
The scratches all seem largely superficial, except for one really glaring flaw. That is less a scratch, and more dent. From the top of the disc down. Which, you'd think would be the death kneel, but here's the thing. Its in that strip of disc the Saturn has where it has the words 'Sega' and 'Trademark' written, that the system needs to read in order to work. I assume this is a copy protection strip of some kind. Well, the dent is in that strip only (I'll try to post an image of this latter.), and its not near the words. But the superficial scratches seem to be obstructing the words.
I've actually managed to get the disc to a the title screen once (usually it can't read the disc and dumps me to the CD music playback screen, which seems to the the default for Saturn Disc read errors)
So I have some hope I might actually be able to salvage this game. But I heard that you can't refurbish Saturn discs, that it'll kill the disc completely. Is this true? Is there any way to buff these scratches out safely? Any advice would be very appreciated.
