Yes game or gamestation should have a disc repairing machine to remove most or all scratches from your discs, i got my oblivion and my fallout 3's scratches removed the other day for 2 quid each and they now work perfectly.
no the disc that your missing had it on it
it depends on how much toothpaste you put on it and how long you left it and the freezer or refrigerator
just rub toothpaste into the disc
Yes, you can buff the surface of a disc with toothpaste to remove, or lessen, scratches.
Well, you can buy a disc buffer. But other than that, it's not real promising. You can wash the disc with toothpaste and it should run a little bit smoother.
toothpaste
For lightly scratches sometimes either Colgate Toothpaste, Or any brand of peanut butter will work.
Yes it does a little...
Yes, you can install a game on your Xbox One and then sell the disc while still being able to play the game, but only if you have a digital license for it. If you purchase the game digitally or if you have previously redeemed a code for it, you can play it without the disc. However, if you only have the disc version and sell the disc, you will lose access to the game since the disc is required for verification.
No No
im 'technically' allowed to tell you but if you go to gamecopyworld.com you can get a game crack that you use if you have 'lost' you game disc (you didnt hear this from me)
The Wii has a read only DVD , so you can't damage the game disc .
