Simple SNES IC question

When wiring a controller using a 520B (Original SNES controller IC) do you need any resistors on the tact switches?

I don't think so.

lemme check. *checks the book*
you need 16 10k-ohm, 1/4 watt resistors.

That's for using two 4021s. Not for using one discontinued original 520B (THe IC in the original SNES controllers).

Did you ground on the back?
