I was wrong,Convert rather than create

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.

OK

Someday Will DB lsd be replaced by .sub?

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

OK, I will create another topic after a while and try it.



There is no error correction code in subcode,
Is there any way to correct the area where libcrypt / securom is currently stored?


Is subdump.exe included in DICUI the same as the above subdump (experimental SubCode reading tool)?

psxt001z doesn't create subs.

If .sub is not listed in DB, is the result of using options such as / s not reflected?

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

Are / s etc. used for libcrypt and securom?

21

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.

convert them into sbi and lsd

Is it for running on an emulator?

F1ReB4LL wrote:

(but what for?

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

What is .m3s?

19

blemm wrote:

What is the difference between .sbi and .lsd?

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

blemm wrote:

Can I create .sbi and .lsd with subdump?

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).

18

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?

If PLEXTOR is not good, which drive is better and which method is better?

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

blemm wrote:

What is unusual data?

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.

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..

I'm sorry.

DB only supports libcrypt and securom subs for now.

Subdump.

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.

No idea. You can try to use IsoBuster under WINE or try to find a similar *nix tool. Or you can rip a couple of separate sectors with DIC, it allows to extract ranges. Like, to rip -5 to -1 and leadout to leadout+5, for example.
