It is plausible that "VRC4f" is supposed to be World Hero


registers[edit]

do the "lower" two address lines for prg registers matter at all? like for vrc4a PRG Select 0, it looks like $8000/2/4/6 all do the same thing? versus say CHR selects where each address in the sets of four means a specific thing. If that's true can we add an explanation of that? As is it's not obvious why those four addresses are specified.
