Changes

*'''[[MAME]]''' The reason MAME doesn't emulate many LaserDisc-based systems, is largely due to indecisions regarding the disc preservation method and format. This will hopefully be fixed in the future thanks to the [https://www.domesday86.com/ Domesday86 project] which employs a combination of specialized hardware and open-source software to preserve the discs in a far more faithful manner than ever before.

It's similar to the difference between "regular" floppy disc dumps and the lower-level captures that devices like the Applesauce or Greaseweasel do. The regular dumps just have the data that you'd see copying the disk on the computer. The lower-level dumps go down to the magnetic flux changes on the disk and are able to reproduce complex copy protection schemes. This allows MAME and other emulators to run copy protected software with the copy protection in place. (A lot of commonly found cracked versions from back in the 80s omitted or defaced the game's content, or were incomplete so that the game crashed on later levels or couldn't be beaten).
