Active ratings have a bitmask of 0x80, and inactive ratings have no bitmask at all. Ratings without the 0x80 bitmask are ignored. 0x40 bitmask indicates Rating Pending. 0x20 bitmask indicates No Age Restriction.
Age limits are set by adding the minimal age to 0x80 (for example, limiting to 12 years and up would give a bitmask of 0x8C)
