    Correcting offspec refresh rate

    As we all know, our beloved snk systems are notorious for having an odd refresh rate

    I am suffering from sync dropouts on my cmvs due to it clocking at 59.45hz

    Is there a way to overclock this to closer to a standard 59.94 by either changing the crystal or something else? Does anyone know the correct value of crystal to do a direct swap?

    Hi Xian Xi, you're referring to this?

    Interesting! Not sure i fully understand how it is operating or implemented, but that's just on me...

    Yes, that's the one. I use the 5v version. All the instructions are there. It works very well.

    Thanks for the response. Having read it a couple of times it Looks.... bloody difficult. Does anyone sell these good to go? I'm pretty sure there would be a market for that with a bit of profit built in.
