Amazing feat. I was a very happy owner of both consoles back in the day, and this port clearly shows how much the N64 brought that "SGI at home" feel in mid‑1996; at least until Voodoo 1 / QuakeGL, maybe even up to Unreal (Glide) or Sonic Adventure on DC?
I still remember gasping when I first saw the basically unattainable (for me) Japanese‑import N64 running Mario 64.
Such an interesting and varied gaming landscape back then; for example, the Wipeout experience on PSX was beyond the N64 port in that particular niche, for its own set of reasons.
