PVD, what systems need it

[sarami]

Ringcodes are useful for predicting possible undumped revisions.

And PVD is useful too. Why isn't there PVD field in psx db?

'Acorn Archimedes' -- I don't have any
'Bandai / Apple Pippin' -- Pippin = Mac, HFS f/s. I don't see any PVDs for Mac discs, but there must be a reason why these are enabled for Macintosh
'Bandai Playdia' -- yes
'Commodore Amiga CD' -- yes
'Commodore Amiga CD32' -- yes
'Commodore Amiga CDTV' -- yes
'Enhanced CD' -- yes
'Mattel HyperScan' -- yes
'Microsoft Xbox' -- I don't have any
'Namco / Sega / Nintendo Triforce GD-ROM' -- Triforce = Gamecube, can't see any PVDs inside.
'NEC PC Engine CD / TurboGrafx-CD' -- no
'NEC PC-88 series' -- no
'NEC PC-FX / PC-FXGA' -- no
'Palm' -- I don't have any, but these are PC/Win discs with palm soft installers, as I understand, so, most likely, yes.

'Philips CD-i' -- yes
'Photo CD' -- no
'Sega CD - Mega-CD' -- yes
'Sega Chihiro GD-ROM' -- I don't have any
'Sega Dreamcast GD-ROM' -- yes, but every session has its own PVD, I don't know, whether they always match or not. Same for the multisessional IBM PC discs, btw.
'Sega Lindbergh' -- I don't have any.
'Sega Naomi 2 GD-ROM' -- I don't have any, same as the next one?
'Sega Naomi GD-ROM' -- yes, same as normal DC GD-ROMs

Thanks.

I don't see any PVDs for Mac discs, but there must be a reason why these are enabled for Macintosh

The old MAC discs only have HFS file system, but after they changed to Intel based CPUs they also included ISO9660 file system to the discs.

General 'Photo CD' is yes.

[F1ReB4LL]

General 'Photo CD' is yes.

Yes, found it, there is PVD after some weird header.

That looks like a PVD to me.

Supposedly, Xbox dvd discs always have the same time stamp for all discs.
I won't activate it for now, but it has to be approved.
