Still no idea about what to return, but can't leave this broken anyway due of a silly check :P

Zero Divide wants CD Seek mechanism to work properly at the intro. It also shows a nice "don't copy" screen (which is unclear if due of a bad image or it's just the way it is):

There's nothing to crack in SS games (saturn ring on each CD was more than enough in terms of protection), either it's a cd seek issue or a weird part of the game itself.

Pehaps it reads a different value in the Subcode Q, who knows ...

This one shows the title screen to me (checking out why it doesn't work afterwards) ...

Name me any game on any CD-based console system (besides libcrypt-protected PSX games) that does that.
And I guess such cases can be easily traced, nope? When it expects something unusual in the Q-channel, I mean.

why so aggressive? afaik the game was done by some demo scene people, and if it was possible to do some sneaky q-channel checks, why not?

I'm sensing a redump / tosec 'subdata doesn't matter!!!' attitude here.

AFAIK 100% of the Saturn library can be burned to CD-R from a bin/cue rip (no subdata) and run properly on h/w with a mod chip/gameshark/bios patch.

No agression at all smile Really, the only console subs-based protection known is libcrypt. Neo Geo CD doesn't count, since it checks for additional indexes only, the sub itself is standard with no unusual data and can be replaced with proper .cue.
We preserve the subchannels when possible (proper and verifiable ones, not like trurip), they just aren't in the main database. This particular dump is from the earlier days, so it doesn't have any subs, but, honestly, this just sounds ridiculous. MESS isn't the first emulator running this title, such protection would be already documented, if existed.
Also, if you've read my earlier posts, you would know, that I'm for complete preservation, including lead-in and lead-out areas, since it's doable and lets you get rid off tocs/cues/whatever - only the actual data dumped from the CD in a single file, like it should be done years ago.

Ok, might be that the Zero Divide video I've seen just skips that disclaimer then. smile
