Sorry, but the answer is no. You cannot transfer Pokemon from DS to GBA games, even through the pal park.
If you transferred a Pokemon from a GBA Game to a DS game through the pal park, it is stuck on the DS version.
if you mean can you get Pokemon from pearl and diamond and trade them to ruby so you can get diamond and pearl Pokemon on ruby. then no you can not. but you can migrate ruby Pokemon. you put the Pokemon in ruby that you want to put on diamond or pearl in the PC. save it turn off. then go to diamond and migrate them. must be in ds at the same time. pal park.
You have to have a ds lite, if you do go down until you see migrate from ruby and then pick the six Pokemon you want.
Probably pearl but ruby can be more expensive at times
No, EX Pokmon do not count as basic Pokmon in the Pokmon Trading Card Game.
the tiles are not in ruby/sapphire they are in pearl/diamond the tiles are not in ruby/sapphire they are in pearl/diamond
Sometimes you need to put Ruby into the Gameboy Advance slot on your DS, then go onto Pearl and look around e.g. route 212, route 214. Other times you need to migrate Pokemon from Ruby to your Pearl game. You can migrate after you get the National Pokedex. == == == == == ==
you don't need any cheats, just put them both in your DS and go to the main menu in pearl right after you press start where palkia is and press migrate from ruby.
you can't get the black flute in leaf green but you can in Pokemon ruby, sapphire and emerald then trade it to leaf green.
you need to stransport it form ruby to pearl
The only possible way is to trade it from Heartgold or Soulsilver(from Pokewalker), or have it put in the PalPark from Ruby, Sapphire, or Emerald.
You can not put action replay on ruby action replay are for diamond and pearl. The thing that you are taking about is a gameshark you con go to Walmart, Target and Bestbuy
I didn't fully understand your question, but if it was meant to mean 'How do you get Pokemon from Diamond and Pearl onto Pokemon Ruby?' the answer is you can't. However, you can put Pokemon from Ruby onto d or p. You need pal park to do this. Hope this helps!
