I need to know how to get saves off original carts without doing the wifi method

I tried to get the saves off my original carts and it always says data transfer failed or something even though I'm connected to the ftp. So, is there any other ways to get saves off original carts?

At www.linfoxdomain.com/nintendo/ds go to "Essential Utilities" and download the "GBA_Backup_Tool_v0.21". You run that on your slot-1 card and it allows you to backup the save file and ROM from the GBA card.
