For those who haven't heard, Kaze is the guy who optimized Mario 64's code, fixed some physics bugs, etc., claims roughly 6x speedup, so that he can make a mod / ROM-hack that runs smoother despite having better graphics: https://www.youtube.com/watch?v=t_rzYnXEQlE

Has he actually released it yet?

Just about a Fabrice Bellard level of competence there

And discovered you could disable cache writeback to have a region of fast RAM without bus contention, and ways to use the hidden 9th bit in each byte which is only usd by certain graphics framebuffer operations.

I don't think he uses either one in serious code, but if he did, good luck emulating it.
