None of the SaveGame managers I find work. I can extract my saves fine, but I can't install them.
I am on 4.3E. I am using a 16gb SDHC card. I also tried these with a 2gb SD card aswell, but its the same effect.
The game I am using is Animal Crossing Lets Go To The City! (PAL!)

SaveGame Manager GX: Unable to Copy Datas
SaveGame Manager Mod: Error! RET= -1
SaveGame Installer: Says its done it, but really, nothings happened.
Everything else: Error! RET= -1

Yes, I already have a save installed on my wii. I've tried it with and without a save. 2gb SD and 16gb SDHC. Nothing works. :(
