Hello, hope im right here

I tried to patch my Save Files from PAL to NTSC-U by using F100. With this tool you can unpack your data.bin file from SSBB.
I tried to just change the name of the folder from 50 to 45, pack it again to a new data.bin and putting it on my sd card. But i get an error when i start my NTSC version of brawl with the new data.bin and it says that the save file is corrupt.
I already tried to download a normal ntsc data.bin from the internet and it worked fine on my NTSC version of SSBB
Hope somebody knows this tool
