HVC stands for Home Video Computer and was the codename for the Famicom during development, this is also the product code for all Japanese games. Note that in the NES Lot Check list ( HNPdata_List.xlsx) it had 3 different codes, HVC, NES and PAL, but all the PAL content was not leaked during the Gigaleak.

When extracted from the archive, two folders are created:

They were located in an archive called Other.7z and the sub archive Famicom_NES.7z. NameĪs part of the Gigaleak the full set of official Nintendo Lot Check ROMS were distributed online on 4Chan. In the Pokemon Leak on the 10th of April 2020 a bunch of excel spreadsheets were uploaded into the /misc folder, these contained the full list of all games that have gone through the Nintendo Lot Check process for most systems up until the Nintendo DS. Every game ever officially released for their platform has had to go through the Lot Check process in order to achieve the Nintendo Seal of Quality. Since Nintendo controls manufacturing of all official games they have a process called Lot Check that ensures the games quality before manufacturing.
