layout with "bb" use bb positions to adjust xor

so you can not just cut bad bytes in dump yourself, then use this layout

You need use original dumps and "Software Bad Bytes" step in mix editor

Also there is strange "AF" partitioin

According to this article
https://en.wikipedia.org/wiki/Partition_type

It can be HFS+ or an ShagOS swap partition
