Hi, i'm not new to the world of redump.org, but now i have a strange problem. Basically i'm interested in preserving games for PlayStation and PlayStation2, so i decided to dump some games i own and make my personal backup for playing on that gaming systems.
PlayStation2 is not the real problem, burning softwares will manage correctly isos. Well, I decided to take a look at the dats and cuesheets and noticed that very very few games for this system use multitrack cdda (about 10 titles), so i eventually decided to use iso as file standard. in this case i had no problems with dvd9s, dvd5s and monotrack data cds (the ones with blue layer).
PlayStation is really a big problem because of multitrack cddas, tracks with errors, libcrypt protection, different versions and so on. Well, i decided to use ccd/img/sub (to make possible storing libcrypt protection) for all my psx backups, but i noticed differences on different software such as clonecd, alcohol120%, imgburn on pregaps, errors and cuesheets. monotrack cds with errour count=0 never gave me problems. for libcrypt protection i added it manually hexediting the sub file with sectors gave on redump instead of dumping from my discs (i tried also sbi2sub utility but seems to generate altered data in the last sectors of sub file, maybe it's the pregap?). so i create my monotrack backup files generating a bin with any software, then creating a cuesheet with imgburn, mounting the disc on a virtual drive, then create a ccd/img/sub from that with clonecd, last if libcrypted game editing sub with sbi2sub. So the data and the libcrypt is not the problem.
What exactly i have to do with cddas and error count different from 0? i read something about c1/c2 errors, compatible drives and so on, but i haven't understood. audio tracks are more sensitive to disc scratches, thus resulting in nearly always crc mismatch (only in audio tracks, first data track always matches). i tried discimagecreator but it's not compatible with my drive. is there any software able to perfectly dump each audio track after first data track without the need of getting a new plextor drive? If yes, maybe you can explain how to configure that, if it is alcohol, clonecd or imgburn?
After dumping i need to burn backups to play (i don't want to use original cds in my playstation), but i noticed that from a perfect dump my drive always generates a bad backup when redumped from burned copy (crc mismatch in img and sub). is it due to pregap and c1/c2 errors? i use clonecd at minimum possible speed (10x, 3x) and verbatim cd/dvv5/dvd9s
