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.

Banks

Variants

HES/AVE released three multicarts of NINA-06 games (HES 6-in-1, Mind Blower Pak, and Total Funpak (HES)), which is mapper 113. The multicart increases the bankable memory to 256 KiB PRG and 128 KiB CHR, and adds run-time selectable mirroring.

iNES Mapper 146 is an inexplicable duplicate.

iNES Mapper 148 is a variant that is cheaper but adds bus conflicts.
