iNES Mapper 031 represents 2A03 Puritans, a cartridge implementing a variant of the NSF mapper.
$5FF8 switches $8000-$8FFF, $5FF9 switches $9000-$9FFF, ..., $5FFF switches $F000-$FFFF, in 4096 bytes out of a PRG ROM up to 1 MiB. At power-on, $F000 is the last bank ($5FFF contains $FF), and nothing changes at reset. These registers are mirrored throughout $5000-$5FFF with no bus conflicts.
As with BNROM and UxROM, there is no mirroring, CHR bank, or IRQ control; this mapper is intended for use with an 8 KiB CHR RAM or ROM and hardwired H or V mirroring.
