iNES Mapper 213 is a duplicate of INES Mapper 058, assigned to by:
Pre-2018 versions of FCEUX as well as current versions of Mesen emulate only the NROM-256 setting with hard-wired mirroring, while current versions of FCEUX implement a duplicate of mapper 58 with some logic for determining nametable mirroring that only works for one ROM (said 168-in-1). Both ROM files run well as mapper 58.
