With just GBA and DS games. You would need:
Emerald, FireRed, LeafGreen, Diamond, and Pearl.
You wouldn't be able to get:
- Mew.
- Lugia.
- Ho-oh,
- Celebi.
- Jirachi.
- Deoxys.
- Manaphy.
- Phione.
- Drakrai.
- Shaymin.
- Arceus.
Mew, and Phione can be obtained via the virtual Wii game "My Pokemon Ranch". Not hard at all.
Lugia, and Ho-oh can be obtained off the GameCube games Colosseum, and XD.
Celebi can be obtained by buying lots of Japanese stuff, and getting it from a bonus disc on Pokemon Colosseum Japanese version. (Costs a lot of monies.)
Jirachi can be obtained in Europe with the GameCube game Pokemon Channel, and in America with the US bonus disc for Pokemon Colosseum.
Deoxys can be obtained if you live in the UK. Senf your FireRed, LeafGreen, or Emerald to Nintendo and they will give you the Ticket to catch Deoxys.
Manaphy can be obtaine off the DS Ranger games, number one or two.
Darkrai can be obtained via the DS game Ranger two. When the WiFi event comes out.
Shaymin, and Arceus are not yet released out side of Japan so don't sweat about these.
Damn I hope you like me and will actually catch all thse yourself, instead of trading for crappy clones. Or else this would of been a waste of my time. :)
