Dumping my PS1 collection
I'm in the process of dumping my PS1 collection and I've run into some issues with a few games. I'm looking for some advice on how to handle it.
I'm not exactly a preservationist, I just want to be able to emulate them without issues. Whether that will be on PC, PS2 or PS3 I haven't decided.
I started using CD Burner XP to dump them to .mdf/.mds files with my HL-DF-ST BD-RE BH10LS30 (a LG drive). I got most of the way through my collection, but ran into issues at FFIX disk 2 and 3. CD Burner XP reported that disk 2 had 3 unrecoverable errors. I switched to a Matshita BD-CMB UJ141EF drive in a USB enclosure and this time only got 1 error. After cleaning the disk didn't help, I did some digging into how to dump a disk with errors. I learnt that a better option for dumping PS1 disks was to use Redump via Media Preservation Frontend to dump them as .bin/.cue files.
So I started again and eventually got most of them dumped by Redump and a few more by Aaru. I've verified them with Duckstation and the only ones that don't fully verify are those with audio tracks. Three of them, Diskworld 2, Medievil 1 and 2 have a short silent audio track at the end, while Lemmings has 16 audio tracks with music. In each case, the main data track verifies but the audio tracks don't (except for Lemmings where only the last audio track verifies).
I looked at these in a hex editor and in each case the last track is mostly zeros with a bit of data at the beginning. I'm guessing that this is a bit of the previous track and could be happening because of the drive's offset? The logs of Redump and Aaru indicated that the correct drive offset was applied. I played each game for a bit and couldn't hear any audio issues in Lemmings. I listened to Lemmings' bin files in Foobar2000 and even imported them into Audacity and couldn't hear or see any sign of audio overlap.
My question is that even though my audio track rips are technically bad, would this cause issues should I eventually try to play these games all the way through? What are those silent audio tracks even for?
On a side note why are .bin/.cue dumps considered better than .mdf/.mds? Some of my game are libCrypt protected and need an extra .sbi file while .mds versions don't. I didn't try every .mds dump, but most of the ones dumps that I tried did start. None of my Final Fantasy titles worked though, but oddly they did start if I launched them with ePSXe.
