Has anyone tried this Dreamcast emulator yet?
It isn't one I've tried myself yet, but noticed a new torrent set for it on pleasuredome posted the other day, so I was wondering how good it was.
The site mentioned loading games from disc, so I'm wondering it it only boots copied games or original GD-Roms. I imagine only CD-R copies as GD-Roms cannot normally be read in a standard drive.
