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.
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!
action replay codes
action replay codes are these strings of letters and numbers that
you enter into a device called an "action replay" and it
temporarily modifies a video game's ROM by reading it differently,
giving you an advantage in the game.
