## Powering the SNES interface

The SNES interface must power the controllers with +5v. This can either be sourced from the parallel port or from from the keyboard, joystick or USB interfaces.

### Single SNES controller

A single SNES controller can be powered directly from the parallel port. Simply add the following components to any of the interfaces:

The connections in the diagram is in addition to the normal interface wiring. If all this sounds confusing - build the SNES interface like it is shown on the DirectPad Pro page: http://www.arcadecontrols.com/Mirrors/www.ziplabel.com/dpadpro/snes.html.

### Multiple SNES controllers

The parallel port should not be used to power more than one SNES controller. +5v for the SNES controllers can be sourced from many places, including the joystick port, keyboard port, USB port or harddrive power cable. You can also use a 7805 regulator with a wall adapter or battery.

### NES PowerPad controllers

The controller (reportedly) uses a lot of power ans should not be powered from the parallel port. +5v can be sourced from many places, including the joystick port, keyboard port, USB port or harddrive power cable. You can also use a 7805 regulator with a wall adapter or battery.
