All of the action replay codes are long because there are so many different codes and games. As a result the creators of the action replay has to make the codes very long so your action replay can identify the code.
Use Action Replay Manager on your PC
What do you do when action replay has no free space when you have no codes?
you make them up!
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.

You can make codes for your Action Replay DS by using the "Trainer's Toolkit". I posted the direct link in the "Related links" column.
i thought this site was good: http://www.supercheats.com/nintendods/pokemondiamondcodes2.htm (make sure you have a ds not a dsi or the action replay won't work)
Make sure you are selecting the codes you desire before you startup the game on the Action Replay DS. If you are doing that, the codes may be invalid.
To make action replay codes for not only LoZ: Phantom Hourglass, but for all games, go to http://us.codejunkies.com/Departments/DS-and-GBA.aspx, and buy the NDS Trainer Toolkit. You can then be able to make your own codes for a wide varaity of action replay codes! Thanks for asking!
What do you mean by an Action replay manager? I can make codes if that's what youre talking about.
