PCE: Mednafen is wonderful
...
the PSG emulator already comes with heuristics... I stripped them off
for Furnace but now that we have acquireDirect() we can give it our
blip_buf and handle everything there
from 40-70% to 10% CPU usage on my phone, and highest quality!

Revert "prepare acquireDirect API" - stupid crap
...
the most POINTLESS plan of all time... acquireDirect.
why? because you gotta fill in the oscBufs anyway, which will take
precious CPU time, so you can't just pass the blip_bufs to dispatch
and hope it'll help by not processing when nothing's happening.
"so disable it when the per-chan osc is up!" NO! we need this for
volume calculation....
"how about rewrite per-chan osc logic?" you know what? I don't have
either the time or the will for that.
now back to Something Else......

where did you get these numbers from? did you make them up?
first you go "bruh bruh bruh" on me and then you drop this. couldn't
you at least look around a bit?!
since when has OPZ been clocked at 4MHz? who said that it does?
the chip's been designed to run at NTSC colorburst frequency, damn it!
on top of that, you didn't have to make up anything. AT ALL.
fixed frequency is simpler than eating with a fork. you just write the
frequency IN HERTZ (!!), the block and that's it.
really? were these numbers necessary?
