Re: RNG Shiny Eggs?
I don't think there's a simple guide. Look on Smogon though. That'll be the place to find anything about RNGing.
RNG is taking abuse of the system that determines if things are shiny, what IVs a pokemon gets etc etc. It's a Random Number Generator (RNG) thats determines these things. So by taking advantage of it and knowing how it works you can control the outcome of certain things and thus get Flawless IVd pokemon or Shiny pokemon and so forth.
