> What I wanted to try and do was something akin to the Super FX chip used in titles such as Star Fox, where the SNES runs the game logic and hands off a scene description to a chip in the cartridge to generate the visuals. Bruh. It's in the third paragraph. > Of course many games shipped with mappers No. You're thinking of the NES. The SNES handled memory mapping natively. The SNES chips had specific calculation functions, or ended up being co-processors, or both. > It's still a very cool hack but I was hoping for some ultra-optimized software-only SNES raytracer when I read the title. Not even the SNES games in the 90s did 3d without an expansion chip. You can't do any raytracing, or any 3d for that matter (without SEVERE compromises) with 3.5 Mhz. If you read the article, the guy designed his own 3 core chip at 50Mhz... Yes it's more powerful than any chip that was in an SNES, but, it's not entirely period-incorrect.
