I'm just getting started on RNGing shiny pokemon and I'm trying to figure out my SID on heart gold. I have a shiny ho-oh I got via SRing and the lake of rage shiny gyrados and came up with different SIDs for both of them (2 different possiblities from ho-oh and a completely different one from the gyrados). I was able to figure out my SID in Diamond rather easily with a natural tentracruel and pichu. Is the method for determining your SID different in HGSS different than DPPt? Also, how can I check easily if I figured out the right SID in HG? I know people offer to do it via AR but I would like to avoid that if possible.
