http://redump.org/disc/6421/ the dump was added in 2009 and no one ever done a redump. Now i did that and i've noticed that my hashes are different from the hashes present in the database. No C2 errors, same exe date, same total sector number. No known revisions or re-editions for the game, so that's probably a bad dump.

Try to byte-compare both images with some tool.

There's at least a retail version with the barcode same as yours (Fr, De, Ita, Nl flags & text on the back) - https://www.ebay.com/itm/371583519183, a retail version with a different barcode (Es, Pt flags & text on the back) - https://www.ebay.com/itm/222934586224, a retail version with one more different barcode (En, Fr, De flags & text on the back) - https://www.ebay.com/itm/323250149362 and a rental version - https://www.ebay.com/itm/152624988560.

For re-editions i meant platinum version or other repress series like "best of infogrames" and similar product lines, where sometimes you can get a # variation, for example. Rentals are like promo discs, 99,9% of the time the disc is identical to the retail release.
Anyway, checking with AptDiff the two files, i found out that all the different sectors in my dump are 00, like this for example. There's a lot of differences, all zeroed sectors, spreaded all over the .bin file. http://prntscr.com/jjr3mr

Can you check it for a possible NoEDC revision? Does yours have EDC ?

Edit: the example on the left has EDC, on the right it doesn't

PX-760A (+30), PX-W4824TA (+98), GSA-H42L (+667), GDR-8164B (+102), SH-D162D (+6), SOHD-167T (+12)

Dumped again, and checked again (just in case something wrong happened before), i can confirm that my disc is a No EDC variant so the other dump is fine, and that explains everything i guess. Sorry about that, i haven't noticed before. You can add this dump as a new variant then, it's not a "fix".

Yep, exactly. Zektoring our older image gives us a Lizard's dump smile

Probably your dump is the NoEDC variant...
You could try to run "psxt001z.exe --antizektor yourimage.bin" in your dump and you will get the dump that is in the DB...

I did that, and now it matches the "old" dump, so both are fine. My disc in the end it's just a No EDC variant. Thanks for your help guys, please add this new dump to the database.

The problem here is that the old dump is from asn007. This guy already had some dumps with EDC differences before (Namco Museum Vol. 5, and also Namco Museum Vol. 4 but that one just happens to be redumped now from a later German print that has EDC). Don't know if that's a coincidence or if some of his dumps were made from backups.

For Namco Museum Vol. 4 + 5, I removed him as a dumper and replaced his dump info with known good dumps, because we can't be sure that his dumps were from original media. Done the same now with this dump.

All his other PSX dumps happen to have have multiple dumpers: http://redump.org/discs/dumper/asn007/system/psx/

NoEDC backups can't have EDC, EDC can only appear on remastered pirate discs. I would leave his dumps as yellow, I don't think it's fine to just delete them without any proofs.

When images are burned and then dumped again from backup, EDC is added. This is why you can't trust EDC variants without proof that they were dumped from original media.

http://redump.org/disc/16103/ -- this one is even weirder, since I don't know any examples of pirate discs with EDC removed.

Only admins can see disc with red status.. Which game is it?

^^ Mobile Light Force

And i agree, there was some weird stuff around his dumps.
