Wow, chop short on posts, that is impressive
His PCE chatroom posts ought to make up the difference.
Very generous of you MNKyDeth, TurboKarma++ for you, but as I already own a full copy of this game, I yield to the rest of my fellow PCE brothers and sisters. Good luck to the winnah!
Add me please. I'm sure I could buff the disc. Awesome waffle!
I saved a few movie DVDs this way. Well, partly. Best if you have the professional equipment, but it can be done.
For me, most of the time, a partly successful buffing job would just let me extract all the sectors with DVDecrypter, and then I could watch it on my PC, or burn a DVD-R for my player in my TV theater center. Getting the original playable itself without skips was tough though... The modern PC DVD drive will be able to extract CRC-checked sectors after a few read-retries with a decent enough DIY buff job, but that was about it for me.
I was too cheap to ever buy the professional equipment, so that's about as good as I could do myself. Just my trusty Makita drill and a $10 buff wheel from Home Depot is how I rolled.
Unfortunately, for CD redbook audio data, it's a different story, you'll never know if bytes are wrongly read as there are no CRC checks. The skips happen because the timing data in the 96-bytes of the subchannel data per sector are misread. The 2352 bytes for the audio sectors could get changed by a few bytes here and there, and you'd never know unless it caused a serious hiss or something. Well, you could use those websites that try to record CRCs of tracks from new/good CDs that work with audio software like EAC or whatever. But yeah.
