Hey, so about RNGing in HGSS. I can't help you right now, but I will be able to another time or in 3ish hours if you're still on.
It will be easier to get started if you download a couple of programs now, if you haven't already. You'll need RNG Reporter, PikaTimer, and PokeRNG, all of which can be found in the All Generations PRNG Help thread.
