# 'decrypt' COMMAND
# Certain file formats (NCCH, NCSD, CIA, FIRM, BOSS, ...) can be decrypted. Use 'decrypt' to do so.

# encrypt 0:/x.ncch
# 'buildcia' COMMAND
# You can build CIA files from certain file formats (TMD, NCCH, NCSD ...). Use 'buildcia' to do so.
# CIA files will always be built to the standard output directory (0:/gm9/out)
# -l / --legit force CIA to be legit (only works for legit system installed titles)
# buildcia 0:/x.ncch
# 'reboot' / 'poweroff' COMMAND
# These are used to reboot or power off the 3DS console
