Yes, you could when they (Nintendo of America) were giving out events however they are no longer giving out events for any of the Pokémon games on the Gameboy Advance so now the only way for you to get any events for any of the Pokémon games on Gameboy Advance (such as Ruby, Sapphire, FireRed, LeafGreen or Emerald) would be to use a cheating device such as a GameShark.
Pokemon/Nintendo events are no longer being held for the GBA Pokemon games (Leafgreen/Firered,Emerald). The only way to get the tickets is with a gameshark
They don't do gba events anymore they only do them for DS's
Yes ,but you need to then go to a Nintendo event but they are done for GBA events.
There are actually a few games with chikorita as a starter pokemon: Pokemon Silver (GBC) Pokemon Gold (GBC) Pokemon Crystal (GBC) Pokemon Soul Silver (Nintendo DS) Pokemon Heart Gold (Nintendo DS) You can also get chikorita as a present for completing the Hoenn Dex in: Pokemon Ruby (GBA) Pokemon Sapphire (GBA) Pokemon Emerald (GBA)
Pokemon Emerald was only released as a GBA cartridge, the DSi XL has no GBA slot so you can't play it.
Nintendo events are dotted around here and there. If it's Pokemon events you're looking for you should keep an eye out on the official Pokemon website.
Pokemon Platinum is for the Nintendo DS, you cannot get it for the GBA.
you would have to have a Pokemon gba game in the gba slot with a charmander in it, have beaten your diamond, have gotten the national pokedex, and unlocked the pal park.
Nintendo events
no im a representitive of Nintendo and we never redo events on the Pokemon games but if you want to find out when they are search Pokemon platinum UK events and go to serribi.net
you ether migrate it from a gba Pokemon game of you go to a Nintendo event
Sadly, you are unable to, You will need to 'transer' the pokemon from the GBA game in the Nintendo DS fat/lite.
