I guess the big test will be running Kaze Emanuar’s code through it.
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
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.
He demos his code on both console and emulator, so there shouldn't be an issue in that regard.
