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?

Use a DFO, that's what I use in my CMVS units. You program the oscillator to the value you want and it will run it at that speed.

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.

Mine are reserved for my CMVS builds. If you have one of my units then I can no problem.
