you can download the code manager from www.codejunkies.com. If the one you want isn't there I would recommended just trying a google search for:
free action replay code manager download
If this doesn't work, then you can reset your action replay.
If you reset your action replay, ALL YOUR GAMES WILL BE ERASED, but you will probably
be able to add in new codes. I DO NOT RECOMMEND THIS. you won't easily be able to get back all the codes you had before. Just to make sure you know what I'm saying, if you reset your action replay all the codes you put on it, and all the codes that were on it when you got is will be GONE, ERASED, DELETED. if you still wan't to reset it do this:
with your ds off, hold a and b. still holding a and b, turn your ds on. when your ds turns on, press and hold start and select( you will now be holding start, select, a, and b).
You will notice that the action replay will take longer to go to the main screen. when it does, you will not have ANY codes on your action replay at all, but you will probably be able to add new ones.
REMEMBER, I DO NOT RECOMMEND DOING THIS!!!
If you did reset your action replay, put in a game( on the main action replay screen) At the top of the bottom screen, or the bottom of the top screen( I can't remember) It will say unknown game and the a code. write the code down. when you have, take out the game. Then insert the action replay. tap the button that looks like a gear. Then hit add new game. type in the games name, then hit continue, then the code you wrote down. hit continue again. the game will then be added. then do what you would normally do to add games. they should work. If it still won't let you add games, then look as hard as you can for a downloadable code manager. if you find one, just hit quick update ( it looks like a ds on your computer screen) this should put the games back on it. if not then try to take it back to the place you got it at. If they won't refund you I would try to get in touch with datel. They will probably send you a new one if you send the old one with the letter ( you should probably mail it not email it). In the letter, ask specifically for a complimentary new action replay.
the phone number for datel action replay support is 0906 550 1236
If you don't want to mail them, the site you want is http://uk.codejunkies.com/support_request.aspx
It will probably take them a while to get back to you. by the way i believe that Calls cost £1 per minute.
Sorry if you have no way to pay from a bank account. You might consider having a parent do it if you call them.
