Ok here it is
This build has support for a shiny new Audio driver... AXPro! this Driver is more optimized compared to the OG Retroarch WiiU Audio Driver also we now have WIP support for Threading this brings a very decent boost to Emulation performance!!
I think everyone will be impressed with the boost
There are a few things you will need to do with this new build...
You will need to lower the Audio Sample Rate:
Load Retroarch, Load the new PS1 Core, Goto Settings>Audio>Output and switch the Audio Driver to AXPro and
Lower the Output Rate (Hz) to 44000.
Back out and go into Synchronization, then reduce the Dynamic Audio Rate Control to 0.000 (cant remember if this is 100% needed now, but doesn't hurt any)
Back out to Main Menu Goto Configuration File and Save Current Configuration.
(Note, if you load another Core, example Snes, the Audio settings you changed will reset to the defaults, remember you will have to go through the steps again when you load the PS1 Core again.... This should change in newer builds)
Now load a game as you would normally, once loaded open the Quick Menu, Goto Core Options>Audio and Enable Threaded SPU.
Back out and Close Content (this will save the Threaded SPU option you changed) load the game again and marvel at the FPS boost!!
Best part the old Speed hacks like disabling Dithering and enabling Fast Lighting will boost the FPS even further so if your game still doesn't quite reach fullspeed make sure to set those options too!
Lastly Remember this is all WIP and a test build
