PAL games with libcrypt copy protection need SBI data #12

Open mr-blackmore opened 1 month ago

mr-blackmore commented 1 month ago

Hello.

So I've been in the process of decrypting games, but I hit a snag with Crash Team Racing (PAL).

The initial dump log didn't indicate any errors:

C:\Users\Private>psxtract.exe -c EBOOT.PBP Unpacking PBP EBOOT.PBP...

However, Duckstation refused to play it. image

This is the only game so far, where I've encountered such an issue.

Actually, the same issue also presents itself with two other games: Legacy of Kain - Soul Reaver (SLES-01301) and Vagrant Story (SLES-02754). All three games have verified hashes with redump.org, so I don't seem to get, what the problem is.

There's some info on this here:

https://psxdatacenter.com/sbifiles.html

I'd really hate to buy anymore PAL games as they don't run on my TV, can you check if the SBI files provided on that site address the problem? and are you getting the md5 mismatch with disc version when extraction completes?

has207 commented 1 month ago

Oh sorry just read your other comment saying you're matching up with redump, so I assume getting the appropriate SBI files should fix the problem.

has207 commented 1 month ago

I guess the SBI data should be in the EBOOT somewhere as well, or maybe downloaded alongside the EBOOT. When I have time I'll see if I can look for it.

Hi again. Thanks for the SBI link. Adding the file to the same folder as the BAN-CUE files (and renaming it to match the files) seems to resolve the issue.

has207 commented 1 month ago

Cool, I'll leave this open with a TODO to look for SBI present alongside or in the EBOOT so that psxtract could do something more user friendly for these games
