The latest BISKey dump combines both crypt and tweak into one line. Changes clarify which key is which and if the last BIS Key, 3, is needed to be copied as well.
Updating the yuzu_copy.bat to create the `%appdata%/yuzu/sysdata` folder if it doesn't exist, and to update info about an error if the rawnand.bin is one complete file.
Tidied up a few errors. Updated yuzu_copy.bat, left the original script alone, but edited in away for the .bat to check if the backup has a nand ID or not.
