According to the guide:
SysNAND is updated (A9LH-only)" has been renamed to "Use SysNAND FIRM if booting with R (A9LH)"
As for "Force A9LH detection" I am not sure, but it's not important. The option is only useful if you launch Luma from HBL, something you will probably never do.
The luma folder is no longer included as it's created automatically when the configuration is saved the first time (it was just a folder with an empty "payloads" folder inside it)
I don't think you need any of those folders.
Okay thank you for all the information, i decided to backtrack to section 1. So after i copy arm9loeader I don't need to copy any of the other folders or files from Luma 3DS, thats it?
