A hobbyist named Tobi has ported Super Mario 64 to the Super Nintendo using the Super FX chip, the same cartridge-based 3D coprocessor that powered Star Fox in 1993. The project, called SMFX, reuses original SM64 assets but required a completely new engine built from scratch. It runs. Not perfectly, but it runs.
The hard constraints are real: a 2 MB memory ceiling threatens to force level culling, and rendering uses a back-to-front painter's algorithm because the Super FX has no Z-buffer. What makes the original worth watching is seeing exactly how Tobi navigates those limits, and what corners of the chip's capability he had to find to make Mario move at all on 1990s SNES silicon.
Tobi has not released the project yet. He stated he will publish it once performance meets his standards. Nintendo never shipped the rumored Super Mario FX title, and there is no documented evidence the project existed. Thirty years later, one developer is answering the question anyway.
