Okay, putting that seed into RNGReporter I can't find any eggs that are shiny with that nature and so on, unless you used International parents, which gives one on frame 44,734, which I'm guessing isn't the one you went for. How many taps and flips did you have to do?
You can set the time/date and then try to hit the delay to get the ideal initial seed for the IRNG, so yes, you can easily RNG to get a shiny Adamant egg.In HG/SS, can the IRNG frame be "calibrated" similar to what is done in the IV step? I'm just wondering if there's any way to accurately RNG for a shiny Adamant (ability and gender don't matter) egg in those games.
