aww man
I kinda saw this coming but when I first opened this thread I got pretty excited because finding a legit prototype of this would be the gaming equivalent of finding the holy grail. Wasn't secret of Mana originally supposed to be a CD based game? I'm not sure if that's just a rumor but if it had been disc based, it probably would've been much longer or just have a lot of anime cutscenes.
tbh I'm glad the Nintendo/Sony deal fell through because it allowed the PS1 to be created, but it's one of those "what if" situations that's fascinating to think about. I remember being hyped for the SNES CD/PS back in the early 90s after reading about it in gaming magazines but fortunately the deal falling through helped create the legendary CD-I with its amazing Zelda games. The animated cutscenes are brilliantly acted and the gameplay was ground-breaking. LJN can't touch Phillips and Animation Magic, and the animation in those games puts Disney to shame. It's too bad you plebes don't appreciate these masterpieces; who needs LttP or OOT when you have Faces of Evil and Zelda's adventure?
I know there's no proof that it's BS yet(I think?) but I'll be shocked if this turns out to be legit.
