If it's the USB version, you can redownload the codes from codejunkies using the PC software.
you just have to bye a new one i guess
You can't. If it's deleted, it's deleted. You will never get it back. Just like all of the other video games.
Highlight either the game or the code you ant deleted, and move to the right bar and press delete. This is waht I do for the replay i use.
When the top Screen is red, don't wait for your game to start. All of your games will be deleted on the action replay. Click the icon on you computer and reset the codes. This will help.
you have to buy the action replay cord you can get them basically at any store that sells games
return your action replay & get another one return your action replay & get another one

Yes, there's a GBA Action Replay, GBA Xploder/Gameshark, as well as the Action Replay Max Duo which works on GBA games.
You cannot: You need the Action Replay DS to input the codes for your games.
If by this you mean "What are all of the games that a DSi Action Replay can be used with?" then you can check on the related link below to see if your game is supported by Action Replay. Action Replay is available for thousands of games and it would be impossible to list them all on one webpage.
