Some questions about adding new discs

[Egen]

1. What is the "Disc title" field? I'm guessing it's what you see when you put the disc into a drive? For example, Orphen: Scion of Sorcery is named ORPHEN. You can see this in IsoBuster. But sometimes a name contains underscores in the ISO layer but not the UDF. Which one to use?

2. How should I format what I enter into the "Ring" section? Say I was entering Suikoden IV into the database. It has a:
Mastering Code, PDSS-012985A1 1
Mastering SID Code, IFPI L331
Toolstamp, A03
Mould SID Code, IFPI QW6A~B
Do I need to input all of these headings myself? Or, does each line down represent something?

3. Should I learn how to check languages myself, or let someone else do it? And how can I let them do it?

1. You can ignore that it is for games etc that have a title attached to it for Example  C&C Red Alert Disc 1 is always called Allies and Disc 2 is always called Soviet. I do not think many people actually utilize it properly around here.

2. I provide them like this. "PDSS-008035A1    1    A08    IFPI L332    IFPI QW84    IFPI QW85 " Take notice of the tab formatting.

3. It is preferred if you check the lang yourself. But if someone gets a hold of the disc/image they can also do it...

Okay, so "tab space" everything with 4 spaces then. However, it seems like in the Mastering Code, the single number at the end only has 3 spaces in Redump entries. Do I still put 4 when creating a new disc?

I guess for languages, if I go into the options menu for a game and there is nothing, then there is only the native language. Thank you for the continued help.




EDIT: Also I'm a little confused about CDmage because it seems it only scans already-created images for errors. I guess I don't know how it all works but I just wonder how it can find an "error" in a bunch of raw data. How does it "know" what an "error" is? Isn't this sort of the point of the website Redump - because the only way to know is to compare a hash? What is it comparing when scanning? Very confusing o__o

[GreyFox]

No. Languages has to be checked by changing the language in the PS2 bios. Since some games have language selectors in game and some have languages set depending on the bios.

Regarding CDMage and errors:

From the ECMA-130 standard:

Code: Select all

14.3 EDC field
The EDC field shall consist of 4 bytes recorded in positions 2 064 to 2 067. The error detection code shall be a 32-bit CRC applied on bytes 0 to 2 063. The least significant bit of a data byte is used first. The EDC codeword must be divisible by the check polynomial:
P(x) = (x^16 + x^15 + x^2 + 1) . (x^16 + x^2 + x + 1)
The least significant parity bit (x0) is stored in the most significant bit position of byte 2 067.

14.4 Intermediate field
The Intermediate field shall consist of 8 (00)-bytes recorded in positions 2 068 to 2 075.

14.5 P-Parity field
The P-parity field shall consist of 172 bytes in positions 2 076 to 2 247 computed on bytes 12 to 2 075 as specified in annex A.

14.6 Q-Parity field
The Q-parity field shall consist of 104 bytes in positions 2 248 to 2 351 computed on bytes 12 to 2 247 as specified in annex A.

Thanks! I'll run all my CD images through CDMage then.

As for languages, I think I'll just leave it blank then if that's okay. If someone wants to contact me about checking the new stuff I add, no problem.

I added NTSC-J Evergrace (SLPS-25003). Please let me know how it came out. I realize now that maybe I should have included the NULL values for the ring in their proper spaces? The ring I submitted is SLPS-25003    2, and that's all there is to the ring. Let me know if there's any way to improve the next entry.

[GreyFox]

Well. If you have a scanner. You can then scan both sides of the disc. That helps to make the information verified.

[Egen]

I don't have a scanner, but I will certainly consider getting one. I'll research some scanners and see which one looks to be the best deal.

On your Evergrace dump you are missing the Mould SID code.
Check the inner clear platic circle of your disc.
It should start with 45..

And just to double check... The serial at the disc "SLPS-25003" contains a hyphen?
I dont think so.
