Its not on DS its on GBA however it can be played on a DS.
you put the game sapphire,ruby or emerald in slot2 on your ds
yes you can they are both the same game.emerald can trade with Sapphire ruby emerald firered leafgreen and that's its. the trick that u can do is migrate your Pokemon from firered leafgreen Sapphire ruby and emerald to fill up your national pokedex in Pokemon diamond, pearl, platinum,heartgold, and soulsilver. U MUST have a ds or ds lite
i don't exactly know because i don't play Pokemon ruby sapphire and emerald i only play Pokemon games for the ''ds'' like Pokemon black and white not for ''game boy advance'' like Pokemon ruby sapphire and emerald
you need to transfer a taillow from either ruby, Sapphire or emerald on a Nintendo ds lite.
There will be a remake of Ruby and Sapphire. Just like there is a remake of Red and Green, and Gold and Silver. A release date is not available yet.
You can't find it in the Sinnoh region, you have to migrate one from Ruby/Sapphire/Emerald.
The only way is through migrating them from Pokémon Ruby, Sapphire or Emerald or by trading.
Its Not too popular yet but come to my site ill help you we have a live chatroom forums and other stuff http://wifimasters.webs.com/chatroom.htm
No. You can either trade it from Pokemon Diamond, Pearl, Heartgold, or Soulsilver, or use the pal park function (if you have an original DS or DS Lite) to transfer a trapinch from Pokemon Ruby, Sapphire, or Emerald.
First, you need to get the ruby and the sapphire in leafgreen, thenyou just hook them up using a cord (you can't do this with a ds, only with a GBA)
There is a thing they are releasing which is free called the 3D pokedex on the ds store. IF you are talking about extenstion as in ruby, sapphire and then emerald, The next Pokemon will be Pokemon grey.
you can't, you have to have Pokemon ruby,sapphire or emerald. you have to catch them and then put the cartridge in the gba slot in the ds. then the screen after the screen where you press start, instead of pressing your file push migrate from Pokemon ruby\emerald\sapphire and go to pal park and find them and there you go!(make sure you have the national dex and you have latias and latios in your PC when you do this
