Seems my version of Burst Nibbler is actually v1.1!!
I can use
raw_dd in disk-utilities to make a working IPF of Burst Nibbler but that doesn't work for Smart Copy (although a CT RAW of the dump will work). I had to rename the protection tracks from Burst Nibbler and use them to make a working IPF of Smart Copy
I guess the protection isn't that special then? You can give Keir more detailed info than I can so hit him up and see if he has time to support it.
