Yes.
you use the Wirless conections
Just find an acces point in ur house with a wirless roter
You can't, you can only get it by trading or migrating
use to evolve pokemon that can evolve only by trading
You can trade whenever as long as you have a GBA to GBA link cable or two wirless adapters you can trade whenever you want just go up the esculator in any Pokemon center then talk to the middle lady or the lady on the far right the middle lady will lead you in the union room but only if you have a wirless adapter, in the union room you can talk to a lady to register a Pokemon you want to trade then you must choose a Pokemon type you want for the Pokemon Example: Say your trading a geodude and you want a staryu you would choose water type for Pokemon wanted then your friend must go to the trading board choose the geodude and then a question will be asked to you say yes and the trade begins. If you don't have a wirless adapter you can go to the far right lady and after she saves your game choose trade center when your in the center take a seat on any chair and have your friend sit in the other, then start choosing the Pokemon you want to trade press A on them then press A on trade then press A on YES for both players then the trade begins. It takes about a minute or 2 minutes because the Pokemon must be traded shown to each trainer and it must make its cry then it saves. You can always use a wirless adapter to go to the trade center as well.
Yes you can. If it is for game boy advance you have to use the trading cable.(can be found in video game stores) For PSP use wireless trading. For psp i am not quite sure. but i hope this helps
No, other than trading the only way to get a charmander in Pokemon gold is to use a gameshark/other cheat device.
I have.
You have to use Action Replay.I'm not sure about trading...
You cannot use that pokemon any more.It's as simple as that.
What you have to do is go to the Pokemon site (or where else you find events) and on the event use via wirless download.KK here is how you can catch some legwndaries! http://serebii.net/diamondpearl/legendaries.shtml
No, but there are rental passes you can use. I find it better to use my own pokemon.
