It is because the Nintendo company are not making any new game cube games that's why I think.
yes they do because i have used ten on mine and they work.
HEY I AM ANONYMOUS SO WHEN YOU BUY AN ACTION REPLAY MOST CODES ARE ALREADY IN IT ........... WELL MINE WERE.
Have someone else do it - JOKE If you have the action replay disc, (comes with it/ about the size of a gamecube disc), you can move the codes from a website to the Action Replay Manager- (the disc) and then if you have the usb cable (also comes with AR) you can download them to your AR. But typing them in isn't so bad I type almost all of mine in and my brothers plus I write them all down, even the super long ones...
well the way u reset it is put ur action replay in hold a+b turn on ur Nintendo ds then when it comes on hold selct and start whilst holding a+b and it should restart your memory (WARNING!!!!) YOU WILL NEED TO INSTALL YOUR ACTION REPLAY DISC IN TO RE ADD ALL OF YOUR CODES BACK ON TO YOUR ACTION REPLAY AS IT ERASES ALL OF YOUR GAMES AND CODES BUT THE DISC IT COMES WITH CONTAINS ALL THE CODES THAT THE ACTION REPLAY CAME WITH
You need an action replay cartride, you can buy it on eBay that's where i got mine for £10.00
Go to a gamestop and ask about action replay and purchase look online for DSI action replay. i found mine @ amazon.com
If you put the game in the action replay, put it in the ds, click the star (*) button and click the codes you want and press start. If your code needs you to press a button to activate it, then you wil have to press it during game play.
yes go to gameshark.com and go to GBA sp and then go to codes then push the letter r for ruby or s for sapphire. that is where i get mine. hope i helped.
There is currently no action replay 3ds, but there is an action replay dsi that works for the 3ds being sold only in the UK. I bought mine on ebay.
it happend to me to but i did't use it for a month after the month i pet it in codes where there!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! yay!!!!!!!!!!! but i did not delete mine i was just playing my game when it froze codes where gone (same as above with my action replay) maybe You Used it to much but i don't use mine every single day i Had to wait Hours to post this answer (storm happend) OK maybe that can help you a bit (true story)
I got mine from codejunkies.com
first you choose your codes, then the action replay saves them on your ds (short term only) then you put the game back in to play the game :) Mine started to work when I left it alone for an hour
