Hi. I'm going to recieve a bunch of PS1 dev discs aka old CD-R etc, and I wonder what's the best method to create an accurately backup of the contents, and what is the best medium to preserve it on. I've discussed this slightly with Jackhead, and he told me about M-DISC. It sounds like a Very durable medium and is physical enough imo. Is M-DISC the way to go? And I want to make the most perfect backups of the content on the discs, but wonder what the best way is. ISO, ImgBurn, something else? Pros/cons? Is it possible to make exact dupes of the content on the discs so it can be moved to a new disc and run on a PS1? How easy/hard is said option? Hope I haven't ignored some super direct guide on how to backup PS1 dev discs. All and any help much is appreciated.
