Trade pool server

Keep the tab in view while you trade: a hidden tab runs too slowly for the game.

A Pokémon that arrives takes the slot of the one that left. Offer it again to trade it straight back.

1. Create a session and send its Session Id to the other player, or join theirs. On a Game Boy Advance with a GB-Link, or in an emulator, they use celio.gblink.io. Both press Start.
2. Whoever presses Start first leads. If that is you, lead a group on the Switch. If the other player was first, the page opens a group for the Switch to join and asks which room.
3. On the Switch: upstairs in a Pokémon Center, the Direct Corner, then the Trade Center or the Colosseum. The other player goes to the same room.
4. Leaving the room on both consoles ends the session. Keep this tab in view while you play.

Trades go ahead whatever either game's progress. Pokémon from Ruby, Sapphire or Emerald may not be tradable out of the Switch's game until it has the National Dex and has finished the Sevii Islands story (Cerulean Cave shows on its town map).

Celio server

1. Mystery Gift has to be on the game's main menu first: answer a Poké Mart questionnaire with LINK TOGETHER WITH ALL, then save. The first Poké Mart shows its questionnaire once you have the Pokédex.
2. Press Start here, then on the Switch pick MYSTERY GIFT, WONDER CARDS, FRIEND, and choose GBLINK.
3. Once the card is saved, talk to the deliveryman in green upstairs in any Pokémon Center.
4. The page stays ready: pick another card for the next one, on this Switch or another.

All of them come from gblink-wondercards. Event distributions and the Project Wonder (Goppier) events are the FireRed and LeafGreen events there, the same bytes the distribution cartridges send. The GB-Link Team's cards are built for the Switch's FireRed and LeafGreen and run on its English games.
