iNES 079

NINA-03 and NINA-06 are unlicensed boards produced by American Video Entertainment. They only differ in the nature of the CIC — the former always has a microcontroller, the latter may instead have a charge pump. The iNES format designates mapper 79 to NINA-03 and NINA-06. A similar mapper for a multicart of NINA-06 games is assigned to iNES Mapper 113.
