You don't. They're stored on the disk and cannot be updated. You have to get a newer version for new codes and the ability to update.
Edit: You can only input AR codes on an earlierversion of the game. It must be before v1.2 for you to be able to input codes.

No, you need action replay for gamecube.
If you mean for the gamecube. Unfortunately not... I have one and I was a little upset about that.
As of 2014, there is not an action replay code to stop time on Majora's Mask for GameCube. There are however other action replay codes available.

action replay
You can't use an SD Card with an GameCube.
No the Action Replay Gamecube will not work with the same codes for Resident Evil 4. You will need to enter the new codes manually to get them to work on the Wii.
you can not put a code on the action replay to play as kafei but then again you cant enter codes on the action replay at all.
go on google and write (game name) gamecube action replay codes
I'm gonna answer my own question: You need Action Replay Gamecube MAX to put codes onto the disc.
Get a Gameshark or an Action Replay and hack it via codes. if you are playing the PC version get sadx memory editor if you are on the gamecube version i can't help you
