Generational loss is something we can't control, compression loss is something we can control.
Generational loss has a minor impact on the video signal, compression loss has a major impact on the video signal.
Which of the two do you think we should worry the most about?
We also can't control laser rot, but we can try to preserve as much of the signal as possible & keep looking for discs in better shape and try to remaster it.

The previous dumps for MAME were done using loss less compression. The problem was they were made with video capture cards, which don't capture all the data on the disc. This has made it impossible to emulate some of the games.
