Then I don't understand your question. "If I create a .sub with psxt001z, does that mean I don't need any other format?" - I've meant you'd better preserve all the subs, not only their lsd/sbi/m3s parts.

Try to ask iR0b0t, he is the only one who has an access to the db...

I was wrong,Convert rather than create

Someday Will DB lsd be replaced by .sub?

psxt001z doesn't create subs.

If it is not listed, it doesn't have a libcrypt/securom protection.

If I create a .sub with psxt001z, does that mean I don't need any other format?

If .sub is not listed in DB, is the result of using options such as / s not reflected?
Are / s etc. used for libcrypt and securom?

Once again: lsd, sbi, m3s contain stripped data from sub files. Some very old epsxe plugins could create them, psxt001z tool could also create m3s, maybe there are also standalone converters, no idea. If you're going to dump subchannels - dump them into .sub, there's no reason to use lsd/sbi/m3s at all, those are obsolete formats used to save some hdd space in the past.

Is it for running on an emulator?

Redump db has .sbi and .lsd so I just want to know how to create it

What is .m3s?

lsd contains more data, but both are technically cut-off sub files.

Directly - no, .sub files only. You can probably convert them into sbi and lsd somehow (but what for? sbi and m3s files are only useable with psx emulators).

The Q channel files (.sbi, .lsd) of libcrypt and SecuROM (~ v3) were in the db of redump, I overlooked it.  (PSX was also at http://psxdatacenter.com/sbifiles.html)

What is the difference between .sbi and .lsd?
.sbi can be created with psxt001z, but how do I create .lsd?
Can I create .sbi and .lsd with subdump?

My Optiarc AD-7200A reads the subs with less errors, for example.

Any non-CD+G data in R-W areas. For example, many PSX games have a specific sequence there that consisists of 0x01, 0x02, 0x03 bytes, Plextor's cooked sub reading mode wipes it.

On this forum.

I don't know any.

I'm sorry.
If PLEXTOR is not good, which drive is better and which method is better?

What is unusual data?

Where can I download subdump?

I'm not familiar with the CD scramble, is there any page detailing it?

Where are the securom and libcrypt databases?

Plextors have weak lasers and they read subchannels worse than other drives. So, don't say "Plextor can read subcode correctly".
They have a pack subchannels reading mode, but it can be used for CD+G discs only, since it destroys any unusual data in R-W channels (same for 0xD8 when used for reading the subchannels in some cases), so, better not to use.

DB only supports libcrypt and securom subs for now.

Subdump.

Even if PLEXTOR can read SubCode correctly, it is not in DB because .sub is unnecessary?
Is there no problem even if the .sub of the protected CD that uses the SubCode is not in the DB?
What is that experimental SubCode reading tool?

Try it and tell us

Depends on whether to fix all the small read errors and mastering errors or not. If yes - can be copied quite easily with stable results. Otherwise, you need many rereads of the same disc on 2-3 different drives. We have an experimental subchannels reading tool if you want to test your discs and drives.
