I have some of the rng stuff down, but I got to get a wild shiny first. I do not know how to rng in hg/ss yet, as I do not know how to advance the frames. The shiny Gyro to my understanding is "pre-set"- thus not wild. Even though you can SR to get the nature/personality, the "shiny" is proggied in. The SID is for "random, wild encounter" which falls under that catagory in the generator "call" numbers. That is the best way I can answer that for you. I can abuse in platnium, (for the most part without the wild shiny I have yet to encounter)but not yet in hg/ss, as the coin flip and "pokie tap" apps are not programed in hg/ss to advance the frames.
