THANK YOU!!! I've been telling this to other dreamcast forum groups for a while now.it would depend on just how picky you were going to get. Neither the Dreamcast nor the PS1 had perfect uniformity for disc trays.
Actually that's not true. Other Dreamcast games that also used the 2 disc tray casing are Sonic adventure (NFR version), Resident Evil 2, RE: Code Veronica and Deep Fighter.the 2-disc trays on sleevecity appear to be dead ringers for the Dreamcast ones. I believe there are only two Dreamcast games that have these trays though. (PSO v1 and Skies of Arcadia.)
As a matter of fact. There are only 2 dreamcast games of the 2 disc variety that utilized the fat cases (with the black divider type) which are Alone in the Dark and Grandia 2.
