Can this be done?

[satenfold]

I'm new to modding my systems and such, so excuse me if this is a novice question.

I want to convert a Nintendo Power Pad to a Star Raiders controller for use with an Atari 2600. Both have 12 buttons.

Can a conversion like that be done without opening up the actual power pad and messing with the triggers inside it?

What kind of circuit diagrams am I going to need to do this?

You'll need something in between, like a PIC or AVR, to convert the signals without modifying the internals of the pad. The NES pad uses a simple serial data protocol to send signals to the NES, whereas the Star Raiders controller uses a diode matrix (I think, that's how the Coleco pad works anyway).

The NES protocol is documented in a few places, but I can't find a diagram or schematic for the Star Raiders controller.
