Nov. 26th: v7 - Support new tsec fw in 6.2.0 and add option to save keys to microSD
biskeydump continues to be updated by scene developer @rajkosto, which is a custom 'payload' designed to dump all your Switch BIS keys for usage with later on with eMMC contents decryption on your desktop or laptop, and his latest version 7 build has been updated to handle all the new TSEC changes made recently by big 'N' with their v6.20 firmware release!
PLEASE NOTE: This only helps in backing up your NAND that been updated to v6.2.0 and making changes to it like downgrading, etc., it does NOT help in getting the new special keys needed for CFW on v6.2.0!
