You have to use the Action Replay DS/DSi Code Manager, which you can install from the disc you get with the Action Replay DS/DSi. To add a game, enter the chip into the Action Replay DS/DSi and turn your DS/DSi on. The chip will tell you it's gamer ID and ask you to give the game a name. If the game has existing codes saved on the chip, it will automatically recognize the game. You can enter cheats using your DS/DSi, or you can use the Code Manager to enter new codes. Remember, using the Code Manager is faster because you can simply Cut/Paste the code.
Just insert the game in the Action Replay DSi. Choose the codes you want or go to the option of adding a new code. You can use the Action Replay DSi Code Manager to insert new codes faster and manage existing codes. You can download it from a disc included with the Action Replay DSi or download it from the online website(aka codejunkies.com). SoulSilver should be recognized by your Action Replay DSi when you go into the 'Codes' menu option.
