Action Replay deleted all of the cheats for Nintendo DS

I can help!~ Your problem, probably, is that you were doing something with your Action Replay and then your DS turned off or died. Here is what you do:

(P.S. Your Action Replay and DS CANNOT be plugged into your computer when you do this.)

1) Make sure you DS is off then press and hold A and B.

2) Turn on you DS while still holding A and B.

3) As soon as the Nintendo screen is displayed, but before "This product is not endorsed by Nintendo" message is displayed, press and hold Start and Select while keeping hold of A and B.

4) Continue to hold these buttons until the Main Action Replay screen is displayed, then release. You have reset your Action Replay and will, once again, be able to put cheats on your Action Replay.

I had the same problem and it worked for my DS.

Happy Cheating!~

did you try to clean the ds slot connector?? you should try to clean the action replay cartridge connector pins...Good luck!!!

When you have the cheats in front of you ,you must check in the box.That will activate the cheat and it may take a few seconds to work in the game...

for this cetain problem you can add the game again
i had this one with my action replay yesterday **** all beter now until broke it again by deleteing all my cheats and i cant add new ones

easy restart it by pushing a and b then turn on and push start and slect whial still holding the other buttons.

You have a bad cheat or a wrong cheat enabled. That is why it's not working. Just disable that cheat and it should work fine.

I'm not sure if you're asking for cheat codes for use with Ridge Racer DS for the Nintendo DS, or Ridge Racer V for the Playstation 2 - Unfortunately, neither game has actual cheats built into them. You can, however, use a hex editor tool (also referred to as a Trainer, Gameshark, or Action Replay), which would allow you to cheat.

I suggest you go to the store where you bought the action replay card and ask the Costumer Service for help. They might give you a replace, and if the replace doesn't work, then it just doesn't work for your Pokemon game. My cousin had the same problem. He bought one of those replay cards and tried one of my  Nintendo D.S. games. It didn't work. When he tried it on his games it worked perfectly, and just 2 of my games it didn't work. Hope this helped !!!!  :D  :]

try, Buying an action replay

put the game INSIDE the action replay. then when it comes to the main menu hit "start"(if it works your son/daughter also has cool cheats!) and if that doesnt work try calling nintendo
