Oh, sorry, I missed your last VM :P
Hmm... well in 3rd gen. there's only 1 seed: 00000000 and you hit it every single time. The way you get different IVs is by hitting a different frame, and the frame advances by about 60 every second. So in order to find frames to hit open up RNG Reporter, and make it Method 2 (For wild pokemon) and Method 1 (For Stationary and gift pokemon and roaming pokemon) and then hit generate. Just leave the ID/SID and the seed blank.
Is that what you were asking? If not then Idk, sorry :<
