Hook up the Purple end or the Grey end to the smaller port on top of your GBA if your using a GBASP its on the back, then hook up the other end to another GBA or GBASP and now your set *Note* It may look like the plug is falling out this is normal it still is hooked up. Also the piece in the middle has a port as well you can connect another cable this and that is how you play with four players.
Yes but you also can trade using a GBA to GBA link cable.
Not long at all once you have both GBA's connected initiate the link by going upstairs in any Pokemon center on both GBA's and talk to the trade center, colosseum or record corner lady to start the link!
You have to have two Game Boy Advances to trade with emerald and ruby and a GBA to GBA link cable, another way to trade is if you use a GCN (gamecube) to GBA cable and you use Pokemon colosseum or Pokemon xd gale of darkness to trade emerald or ruby Pokemon to there then use colosseum or xd gale of darkness to trade your emerald or ruby Pokemon to the other game either ruby or emerald. Theres no way you can use a DS to trade with GBA games because the DS is not compatible with the GBA link cable.
Yes, so long as you have a GameCube to GBA Link Cable.
Your ruby is probably corrupted somehow you can try to use the berry program to fix it to do the program use Firered and go to the title screen pree B and right and start you should appear in the program press A until it says turn on the other game boy advance and hold select and start on that gba make sure a GBA to GBA link cable is hooked up to your gba with ruby in it and firered in the other and make sure the correct color cable is in the right GBA theres a purple cable and a gray cable if you read the instructions it will tell you what to do.
Use a GBA link cable.
Yes. You must use the gba-gc link cable.

The GBA universal link cable is the only way to link two GBA's together, sadly.
Yes.

Either use wireless adapters or use the GCN to GBA link cable to trade a poliwhirl holding a king's rock.
No, the DS cannot be connected to a GBA either by link cable, or by the DS' internal wireless, to a GBA using a GBA wireless adaptor. The only form of linking they can do is to have both the GBA and DS cartridge inserted into the same DS, to use functions like migration in the Pokemon games.
Yes, but it still requires a link cable for the GBA to GameCube.
you can't a GBA link cable can't connect to a DS.
There is a opening in the link cable for another link cable to be inserted into that which then can transfer to the other GBA's.
yes
