Quote: As far as I'm aware, it's just a matter of getting the right kind of capture, but to do that, it's a matter of finding the right kind of person with the right kind of hardware.
There's supposedly a specific type of LD player which has hardware where it's (reasonably) easy to tap into its circuitry right after the just-read sample has been converted from analog to digital, as well as a bit indicating whether or not the conversion was successful.
If that's the case, then getting bit-perfect dumps should be as simple as hooking a logic analyzer up to that specific type of player in that specific spot in the circuit, and then running as many copies of the same disc through the player until there are no samples for which the "sample valid" bit was not set.
Thanks for the info Moogly. From what OG said in this thread there doesn't seem to be any developer with the hardware or the know-how to capture the discs as you described. Would it be possible to use existing captures available and encode them with the necessary frame information? Then later be replaced with the flawless encoded copy (if it ever happens at all). I'm sure the existing Cube Quest CHD can be replaced with a bit-perfect one when the time comes, correct? I noticed over the years roms are updated/replaced as better dumps are found why not LD rips? Forgetting DL & SA as there are legal issues there are still many LD games that could use some TLC. I think I remember someone saying there was access to the prototype Gallagher game.
I remember reading a comprehensive description of how LDs work on Aaron's page. I remember him using a program called Direct Show to encode Cube Quest with the necessary information. I'm not sure encode is correct word to use.
I know the discs are getting old and will definitely succumb to bit-rot. At that point there will be no way of getting a perfect rip.
I want to personally thank you for taking a stab at Stunt Cycle. It also seems to have brought back couriersud. He continues his black magic. I think this is all a deception and he is really trying to take over the internet.
I wish someone could explain his progress (in laymen's terms).
Thanks again for the response and I will keep my fingers crossed that some LD progress will come in '17
