You need to save at a pokemon center in which there are no WNPC's. The pokemon centers at the Pokemon League and at Castelia City have no WNPC's for BW1 and BW2, respectively. Choose Wondercard as the Method over GLAN because Meloetta is genderless. The IV's are based off the PIDRNG unlike wild or stationary pokemon. Input desired IV's/nature, set the Min/Max number of advances and search for seeds. You can advance the frame by using chatters. Talking to the delivery man also advances the frame, in most cases.
Talking to the delivery man advances the frame by 1.
Thanks for the quick answer. I´m not sure if I completely understood you so could you tell me if those steps are correct when rnging that specific event meloetta (Im using Pokemon black 1 if it helps)?
1) 5th Gen Time Finder-> Capture -> Method: Wondercard
2) Type in the desired IVs and nature and tick the box "Shiny only" for shiny results
3) Min/max Advances lets say from 0 to 150 (
Do those advances refer to the PIDRNG Frame or the other Frame which is increased when walking 128 steps etc. ?)
4)When I get a result, go back to the main window of RNG reporter -> Method "Wondercard (5th Gen)", then paste the seed and hit "Calculate Initial PIDRNG Frame". The number of required chatters will be (Target Frame - Initial PIDRNG Frame - 1) since talking to the delivery man advances the frame by 1.
Are those steps correct? A problem I faced was that after hitting generate in the main window, there´s no extra column which indicates shininess? Does it mean wondercard Pokemon can´t be shiny?
