Build an ISO?
 

Am new here, hopefully this thread is in the correct place.

I have an old game that I'd like to install but keeps getting stuck when I try to. Think it's because there must be some bad sectors on the disc.

Would copying all of the files manually to the computer and then building an ISO to run with Daemon Tools or perhaps burning them to a new disc work?

The game is a Dual Layer DVD, if that's of any importance.

thats a question you can answer for yourself.. just try it
also try cleaning the disk

(For cleaning, try the "toothpaste method".)
