The IV frame advances by walking 128 steps, the amount of frames advanced is directly related with how much 'mons you have in your party (ex. you have 4 'mons in your party and you walk 128 steps, then your IV frame advances from 1 to 5). I don't recommend you to use that method, specially when you're just RNGing your first stationary 'mon.Thanks for the answers. n.n
So the Iv frame doesn´t increase? As a long I land on my seed correctly and I start the fight with Latios, the Ivs will be correct or im missing something? That´s why you suggest to find a correct Iv spread at frame 1?
Sorry if all of this sounds dumb, but its my first time RNGing stationary legends at Black 2 using a DSi.
Correct, the IVs will be correct by just hitting the right seed.
