iNES Mapper 079 denotes the 72-pin NINA-03 and NINA-06 circuit 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.
iNES Mapper 146 denotes the 60-pin Sachen 3015 circuit board, which is functionally identical.

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 148 has the same bit assignment in the data latch, but moves the latch register to the CPU $8000-$FFFF register, introducing bus conflicts.
Errata
For mapper 79 but not 146, FCEUX additionally implements a CNROM switch at CPU $8000-$FFFF, apparently to run a few mapper 3 games that are incorrectly set to mapper 79 in GoodNES 3.23b.
