-[[iNES Mapper 023]] is used to represent the [[VRC4]]e (PCB '''352396''') and VRC4f (unlicensed games) variants of the Konami [[VRC4]] mapper and the [[VRC2]]b (PCBs '''350603''', '''350636''', '''350926''', and '''351179''') variant of the Konami VRC2 mapper.
-For details see the following:
-* [[INES Mapper 021]] / [[VRC4]]
-* [[INES Mapper 022]] / [[VRC2]]
-Note that the VRC4e variant uses different address lines to select registers than the VRC2b and VRC4f variants. Your emulator implementation must either combine address lines (like FCEUX; bitwise OR is good enough), use checksums, or NES 2.0 submappers.
