Your Action Replay DS hardware may require resetting if you are experiencing any of the following problems:

* Code Manager PC software is reporting that Action Replay DS does not contain enough free space when it actually contains no codes.

* Code Manager PC software is reporting the console`s battery is low when it’s actually fully charged.

* Multicolored bars are shown on the screen after you confirm the entry of a game ID when trying to manually enter codes.

* You can use the Code Manager PC software without any problems until the Action Replay DS is connected via USB set to the update mode on the console, at which point Windows shows a run time error.

If you are experiencing any of these problems, please follow the steps below to reset the Action Replay DS hardware. Please beware that resetting the Action Replay DS hardware will not restore a default codelist, and any codes which are stored on the Action Replay DS will be erased.

1. With your console powered off insert the Action Replay DS

2. Hold down buttons A+B

3. Turn your console on

4. With A+B still held down, as soon as you see the Action Replay DS license screen press and hold down buttons START+SELECT so that you now have 4 buttons held down

5. Hold all 4 buttons down for around 10 seconds until the Action Replay DS loads to it`s home screen

6. If Action Replay DS doesn’t hold on the license screen for around 10 seconds when you do this, you may need to turn off and try again

when you turn on the action replay and see the logo, hold down start & select then turn off your ds. turn it back on, but when you see the ds logo, hold down a&b. then it shows the action reply. your action replay is reset so now, update it with the code manager.

try putting the code in a couple of times then try without the - and then put the id code in fully with the - and hopefully it works

Don't return it! Your Action Replay DS is corrupted. To fix it, turn the DS on (with AR in it) while holding A and B. Then, at the white screen, after "Nintendo DS" but before "This product is not licensed or endorsed by Nintendo", hold down Start and Select while still holding A and B. A few seconds will pass and then the title screen will appear. A few seconds after it appears, release all the buttons. The screen will go white, so just restart the device. Now do a Quick Update in Action Replay Code Manager (on the PC) by pressing the Quick Update button in the corner of the window while the AR (still inserted in the DS) is connected via USB. After it's done, viola! A fixed Action Replay.

i have had a similar prob it wiped all the games andm then i could not put more on because it went multi coloured when i tried so i hap to reset the entire thing to do so(source codejunkies):

I CAN SOLVE IT xD no its not broken

heres what u do :D You hold A+B+START+SEL With action replay in then you turn it on while holding Those buttons then when Action replay main screen comes up Release the buttons and then type ID in then it should work

i had that problem but now its simple
1.with console off hold a and b
2. still while holding a and b power up
3.as soon as the the ninten stating before this product is ... press start and select and a and b you should be all four
4continue until Main action replay screen is displayed the release it is reset now continue adding you codes

First, turn on your Action Replay, and after the warning screen for the DS Pops up, hold these four buttons: A+B+SELECT+START, the white screen will stay up longer than normal, but just be patient.

When the menu screen pops up, let go of the buttons

Plug your DS (Action Replay) to your computer and you should be ready to input games and codes again.
