These are generated by converting the age rating(decimal) to a hex value and then adding it to '0x80'. For example if '7 years' was the rating, then the flag would be 0x87.
Active ratings have a bitmask of 0x80, and inactive ratings have no bitmask at all. Ratings without the 0x80 bitmask are ignored.

This flag is what the Home Menu uses in order to determine the [[Home Menu#Region Lockout|Region Lockout]] of a title. This exists inside the ICN data as little endian. (In the table below they are presented in big endian)
This flag is what the Home Menu uses in order to determine the [[Home Menu#Region Lockout|Region Lockout]] of a title. These are bitmask flags. Byte[0] is currently the only byte used, the rest are reserved.

As these are bitmask flags, multiple regions can be 'allowed' access to a title if Nintendo chose. A "Region Free" title would have each byte = 0xff. (For reference, the CTR_SDK implementation of "region free", has bytes[0-2] = 0xff, and byte[3] = 0x7f)

For example, if we wanted an application to use the 3D effect, autosave on exit and use save data. The combined flag would be 0x95: (0x01 | 0x04 | 0x10 | 0x80)

=== EULA Version ===
This is the EULA version which is checked when the Accept EULA flag is set, the version is compared to one stored in the 3DS. If the SMDH version is greater, then the user will be prompted to accept the EULA.
