Ah, then that makes sense! I was tackling the issue from the wrong end. I was wondering why when I loaded up sound roms that I got nothing but a bunch of memory writes to addr 0.
It will be interesting to see M1 evolve in that fashion! I love the plans.
I sincerely thank you for your time! I'm going to continue to prod around on the Mac codebase in the meantime because its fun.
