Did you add the XML file?I can't get this to work with Ninjhax2 on a Japanese New 3DS [9.9.0-26J] using the eShop version of Cubic Ninja. Whenever I launch save manager, it gives me the "Could not access the savedata archive! Press X to exit." error message. Pressing the D-pad doesn't do anything. I also updated the boot.3dsx afterwards, but then the homebrew menu doesn't let me open the app because it says it can't find a source target. Does this app only work with physical cartridges? I'm trying to backup my digital saves, so if it only works with physical cartridges I'll just give up (I don't have any physical cartridges to backup). Any help would be appreciated.
