Please help me make my pokemon Wifi Ready

[Prideless]

The pokemon I have are not created from scratch they were either caught or hatched then modified afterwards.

I have been reading a lot about PIDs and their correlation to Abilities, Natures and IVs however I am still very new to this and it seems the ones I caught in Black and White I modified IVs then gave legal PIDs(Pokegen) and it worked on going on wifi.

However I have pokemon I really DID poketransfer from Pokemon Pearl and they were hatched and EV trained(/w PKRS) in Pearl I then modified their IVs/Nature/EV Spread in Black and White then gave legal PIDs.

These pokemon that I have transferred I modified afterwards and gave legal PIDs dont work on Wifi.

Can someone please explain to me how can I get them wifi-legal.

Id appreciate if someone can explain to me how to get my pokemon wifi-legal that legitimately came from pearl just modified after I transferred them to B/W.

Thanks.

Hippowdon should be marked as hatched because he has an egg move (slack off) also in gen 4 if a pokemon is shown as hatched it can have any PID it wants and still be legal.

Ok a quick update Hippowdon seems to be a bit different as its not marked as hatched it says grass wild. I think I may have pokesav'ed the move Slack Off onto it afterwards when I caught it in Pearl.

Now the weird thing is Hippowdon works on Wifi however Garchomp,Tyranitar,Gliscor do not. How can I get them working?

Im pretty sure those 3 I actually were eggs than I hatched in Pearl.

and how do I make it appear as hatched? Its already hatched so isnt it supposed to be already set?

so your saying any hacked pokemon I bring from GenIV has legit PIDs on GenV?
