FS.kip1 savedata CMAC verification skip guide

How to patch FS.kip1 in order to disable savedata CMAC verification (letting you transplant savedata from other consoles):

Get kip1decomp from https://files.sshnuke.net/kip1decomp.exe or compile yourself from https://github.com/rajkosto/memloader (x86 only)
Get xdelta3 from https://sourceforge.net/projects/xdelta3-gui/ or similar

Get your existing FS.kip1 by getting the INI1 from your Package2 using hactool, and then extract the INI1 to get all the builtins
Download appropriate CMAC verification disable patch and place it into the same directory as FS.kip1:

Run the following commands, replacing FS_PATCH_FILENAME.vcdiff with the actual filename for your version
   kip1decomp d FS.kip1 FS.decomp.kip1
   xdelta3 -d -f -s FS.decomp.kip1 FS_PATCH_FILENAME.vcdiff FS.patched.kip1 <- errors here means the patch doesn't match your FS.kip1
   kip1decomp c FS.patched.kip1 FS.kip1

Place the new FS.kip1 onto the root of your microSD, as well as adding the following line to your hekate_ipl.ini launch configuration:
kip1=FS.kip1
