[DONE] Sega Dreamcast: Multi-Cue > GDI

[user7]

Sega Dreamcast is heading towards a PAL and USA fullset. A friend has offered to grant me access to his USA DC fullset after Christmas (pending I can raise shipping funds), and AJ and I are working on a video dumping guide.

As USA / PAL DC sets begin to wind down, we're in need of a better solution for emulator developers to implement support for the redump DC sets.

Fireball has expressed interest in shifting to a multi-cue format instead of GDI, and I believe that would be the best move to make. If redump could implement multi-cue, I would be happy to get into touch with emu devs to bridge the disconnection between what we're doing and what they're doing - allowing the redump DC sets to actually be useful.

Emulators, both software and Optical Drive Emulators that replace the disc drive in a real Dreamcast, do not currently support Redump's GDI dumps as the format was simply not designed to accomodate for the way we store our dumps. It's important that for our dumps to be useful, at all, that we store it in a more appropriate format that emulator developers will be willing to implement.

[Hiccup]

I assume this new format would be just as accurate?

Yeah same data / track hashes, just easier for devs to access.

We'll be fundraising soon for the redump DC set, so "hey we can't use any of your dumps" seems like a pretty accurate criticism people might have, and emu devs won't be adding GDI support beyond what exists. With multi-cue and diplomacy, i'm sure we can get support added.

So if data / track hashes stay the same, what's the problem with emu devs, can't they just generate the cues internally on the fly?

No incentive. They're happy with the TOSEC sets. This makes the Redump sets completely worthless / useless in all practical sense. GDI is an all around terrible decision. You may as well have asked "Why won't they wipe our asses?"

[iR0b0t]

GDI format lacks of track pregap length, which is needed for generating the cues. That's the main reason it can't work.

[user7]

Add placeholder pregap lengths? Not seeing how that would be any worse.

Right now the Redump DC set is a problem. Emu devs won't touch it. This is a fault of the redump DC system and an issue that needs resolution.

[Jackal]

"multi-cue" is a cuesheet with multiple binary tracks, like we have already for the other systems? Multi session PC discs also have a "normal" cuesheet. So all that is needed is to replace the gdi download with .cue?

IIRC this would also allow submission of unlicensed DC discs such as Action Replay / GameShark.
