Yes, since 1st gen.
I have a stupid question... I played Diamond after beating Pearl, and I were in a rush to finish battling E4 so I skipped a lot of items. Well, the question is... where do I get my Pal Pad?
You can get the pal pad in the basement of the Oreburgh City pokemon center (or any pokemon center basement after that). Go down stairs in one of the pmon-centers from Oreburgh city on and talk to the lady behind the desk on the right.
