Has the prototype of Beavis & Butt-Head for ps1 found ? or dumped ?

I have seen some pictures of the game itself and it looks finished. It just never got released since the show was being cancelled at the time.

I'm pretty sure someone has it. Either it was DreamTR or maybe buyatari? I feel like I remember seeing the disc and shots of gameplay somewhere.

i haven't heard of it to be honest.. but i'm not that into prototypes
mr gimmick is tho
