loopy made this a while ago for us at NESdev to render audio out of a PowerPak so that it had less PPU noise. Press "Start" to turn the PPU off when playing an NSF.

Put this in your PowerPak directory. Smile

Thanks for that...I'll test it out when I'm doing the resistor mod next week.

I've had bad experience with a resistor mod as the expansion audio levels can never be perfect for all expansion carts/flash carts.

Please consider using a potentiometer instead so you can adjust the "mixer" levels.

Sorry, yeah I meant putting in a pot. I just need to do the research, as it's a bit more complicated than soldering a resistor between 2 pins.
