tildearrow 11c99f9f96 PCE: push it even further! 
now a bit faster
 2025-03-04 12:21:56 -05:00
tildearrow f0a3e3f590 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!

TODO:
- PCM
- chan osc (should be very easy)
 2025-03-03 20:29:34 -05:00
tildearrow 8f54445625 GA20: acquireDirect optimizations, part 1 
buggy, slow and glitchy
output is good but chan osc is now broken

from 1.5 to 0.4 seconds
 2025-03-02 20:29:28 -05:00
tildearrow 49a8693dcb new chan osc, part 7 
i am done
 2025-03-02 16:14:49 -05:00
tildearrow 6265d2cd39 new chan osc, part 6 
more adaptations

how can I get you out of my head... I want to go back to work!
