What does it mean when action replay is unable to download codes because it does not have enough space to write a file?

connect acton replay to pc
load the code manager
right click on the program in the top lerft of screen
choose about action replay from the pop up menu
click on the reset action replay button

you will lose all codes on the system but it should work
hope this helps ya

when u start up the ds hold a and b when the nintendo logo comes up hold start and select, that will fix it

You can fix the device just hold a+b then turn on the ds still holding a+b when it says this product is not endorsed by nintendo just hold start and select now you are holding 4 buttons continue to hold these buttons until the main action replay screen its displayed,then release.Now connect the action replay to your computer and now it will accept every code you want.I hope this was useful for you.

You need to reset the action replay card.

The codejunkes website has the answer on the website

It's not an error. Action Replay is a cheap, silly hacking device that breaks every so often.
It may have been a codelist corruption.

my answer is that action replays do that they **** i hate them they mess up all the time

all you have to do is turn your ds on then hold a+b+start+select

I have just found the solution to the problem (2 minutes later XD)

Try resetting the Action Replay by following these steps:

1. Insert the Action Replay into the DS
2. While the Action Replay software is loading, press and hold all the following buttons: A + B + Start + Select.
3. Release all of the buttons once the Action Replay is at the main menu.

The first screen should persist for much longer than normal, and when the Action Replay DS main menu loads, your hardware should be reset.

Once the reset has been performed, try connecting the USB cable to your PC, opening up the code manager software and transferring data again.

It won't return all of your games back, but it will allow you to start on a clean slate again. (Using the update feature will bring most, if not all of your games back
