I do have the HGSS shiny egg box checked. i always use a frame of 1 for getting the right nature, but i know my SID isnt wrong because it never changed from 7 months ago, but for some reason its not working now, and ive done it with 3 eggs, one gyarados one garchomp and one metagross. I have a swampert ludicolo tyranitar dragonite umbreon starmie kindra and vaporeon to prove that i have managed to do it more than once. unless gyarados and garchomp have something other than 50/50 gender and metagross does have a gender i dont think im doing anything wrong. on another topic, is there a way to RNG for BW? would really love perfect hydregion!
