You have to buy two games and two Game Boys and a link cable and trade in between the games
if u have two gba games on a gameboy advance then you need the link cord to connect them if you have two games on ds such as Pokemon pearl and Pokemon platinum then when you just stand next to each other p.s. you go upstairs in a Pokemon center
No. Since it is another generation of Pokemon, it is impossible to link the two games.
You'll need Pokemon ruby. If you mean ruby to sapphire, then you'll need both games, two gba's, and a link cable.
you can't unless you have two games and two game boys with a link cable. If you have those you can start a game get the Pokemon trade it to the other and start over again.
To connect the Time Machine when using Pokemon Gold you need two gameboys, and a gameboy link cable. Be sure that the cable is compatible with the two systems.
You cannot trade between Pokemon Ranger and Pokemon Diamond/Pearl. The transfer of the Manaphy egg is simply an event and the two games cannot link for any other purpose.
Pokemon Gold and Silver are gameboy colour games. If you want to trade Pokemon between them you must have two gameboy colours and a gameboy colour link cable.
To evolve Machoke you will have to either have a buddy with a GBA and FireRed/LeafGreen + a link cable or just two GBAs two games and a link cable. In other words you can't do it with one Game Boy Advance.
you need a link cable EDIT:and two gameboys.
First, you should have two GBA's and a GBA link cable. Make sure you have gotten the Pokedex on both games and have at least two Pokemon in your party on both as well. Go to the second floor of the Pokemon Center and go to the second booth, talk to the lady, and you should be able to trade between the two games.
Unfortunately, you need to use two GameBoy Colors with the GBC link cable. The GameBoy Advance connects at a different frequency than Gameboy Color games can receive.
