Also, upon further investigation it appears that changing the clock will not effect the speed games run but only the pitch of the audio.
I'm wanting to change the speed games run. Audio would be cool, but primarily I'd use this for playing games. Is there any known way to increase the speed games run?
I want to assume that it is the xtal pictured in red here:
I cannot guarantee that until I open up my own NES and poke at her. Then again, there ia another oscillator to the toward the power/video board. It looks as though it could be this type of outoput, but idk just yet:
EDIT: Yup, I believe it is the red one;
According to that schematic, it runs to both the PPU and CPU. Make sure you only increase or decrease it in small increments because I cannot find any information of others doing similar.
It is a different type of crystal than the ones we used in the board I made, so you would have to cut PPU-pin-18 but not CPU-pin-29 to use it. At this piont, you're dealing with black magic and I don't really suggest going there without the input of others.
