No, I mean you didn't show up under the in-game PSS friends list even when you were online on my 3DS friends list. Is some kind of special method required to trade Pokémon between XY and ORAS?
Yeah, that's likely because I was idling at the time offline. If you're playing XY/ORAS and are online, but go to the Home menu and view your friends list, you'll be online on the 3DS but offline in-game. There's no special method required to trade between XY/ORAS, just that some items and Pokémon with certain moves (ORAS items/moves like the Salamencite or Dragon Ascent/Origin Pulse/Precipice Blades) cannot be traded from ORAS to XY. =)
Today's gonna be a busy day for me but feel free to message me in VMs or somethin' when you'll be around, I have to clean my room and do the laundry so I'm gonna be preoccupied for a bit. xD; I'll be idling in Omega Ruby the next little bit.
