UNIF to NES 2.0 Mapping

This page aims to list the NES 2.0 equivalent header values of all known UNIF board names.

Notes:

  • Empty cells mean mapper-controlled mirroring and zero amounts of PRG-RAM, respectively. An empty CHR-RAM cell means zero amount of CHR-RAM unless the cart has no CHR-ROM, in which case it has 8K of CHR-RAM.
  • Unless mentioned otherwise, PRG-RAM can be battery-backed if an UNIF BATT chunk is present. Boards using both battery-backed and non-backed RAM are denoted using the non-backed amount first, followed by a plus sign and the battery-backed amount.
  • Common prefixes such as BMC-, BTL-, HVC-, NES-, UNL are omitted and replaced with *-.
  • Compatible boards with the same stem but different prefixes or additional suffixes are not listed separately. For example, *-NROM includes NES-NROM-128-02 as well as IREM-NROM-128 as well.
  • Board names are shown capitalized and with leading and trailing space characters removed, even as some UNIF image files do include MAPR chunks with leading or trailing space characters and lowercase letters.
  • Because the tables do not list the maximum PRG- and CHR-ROM sizes for each board type for brevity, a reverse lookup of the correct UNIF MAPR for a given NES 2.0 header is not directly possible.
