A private collector in Sweden owned a 2000 era copy that was handed off to a preservation group who modified the rom file to make it playable. Then they uploaded it to the Internet Archive, both in original and modified forms:

It is playable in Project 64, but I only got into the game before it crashed. I am running an older version of PJ64. I will investigate other versions later today.
