No screenshots :(

Are there any pictures or video of it running? I understand why they are not on the GitHub page

There was also just recently a Dreamcast port made, as well as Mario Kart 64 for multiple platforms.

If you like this port, you may also enjoy this ground-up effort to clone SM64 on the GBA https://youtu.be/nS5rj80L-pk

> Tessellation (up to 2x) to reduce issues with large polygons

From the videos I've watched there is still insane amounts of affine transformation texture warping, is that because it's not enable or because 2x is not enough?

I guess they will need to also redo all level geometry to be more amenable to tesselation... I guess that's why many ps1 games had blocky looking levels.
