Yes
An action replay is for cheat codes used for ds games
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.
Well for the action replay dsi when it loads you will see all the games if you only have action replay ds then i would Google search it. Most of the Mario games work. But not all games work.
just chose him at the biggining. of the games
yes they do work because there is no Australian action replay or game shark yet i use a European action replay for Australian games.
