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.
