Service Access Control
This is a list of service-name strings which the title has access to, with the following structure:
+0: control_byte +1: {service-name without nul-terminator}
Bitmask 0x0F in control_byte is the {length of the service-name without nul-terminator} - 1.
Bitmask 0x80 in control_byte means service is allowed to be registered.
The service string can contain a wildcard *
character.
FS Permissions
Bit | Description |
---|---|
0 | MountContent* is accessible when set. |
3 | This is only bit set for ShopN in the permissions-u32. |
