This is the Action Replay software for the GBA that was released in 2002 from Datel. As far as I know of, it only works for the Action Replay in the clear case with the USB-B port on the side.
Datel does not have this on their support site anymore.
Just do the following:
Extract the files.
Burn the files to CD. They are in CD structure, not ISO.
Place the CD in the CD-Drive, then install the software using the autoplay function.
Leave the CD in the Drive and connect your AR (while in your GBA) to your computer and turn on your GBA.
Your computer will automatically install the drivers and you will be adding codes in no time.
