[quote name='Berzerk']So the Micros require a power, but the GBA ans GBA SP don't? That doesn't make sense, but then Nintendo never does....The things is, I don't think the direct through capeles have an IC. That is what I am getting at. (The Nyko ones) If they did, then they would have to be built right into the connector pin. Based on the size of the IC, I don't see how they could fit it in either end of that cord. Also, the Official Micro-Micro link cables use an IC, but my old Madcatz GBA/SP-GBA/SP does not use an IC, so I am thinking that Nintendo added the IC just to be r3tarded. If some one has an old gba-gba official Nintendo cable, and it has an IC, then my theory is even more likely.[/QUOTE]
The Cube-GBA-cables require a power supply from the GBA / SP as well (if you open up a converter cable, you can trace the appropiate pin). If you really want to try, you could build a GBA Link-extension cable without the power wire. It should work with most link cables but not with the Cube-GBA-converter.
About "Nyko-cable, ICs or not?":
Nyko-cable uses six wires. So GBA-power is connected somewhere. As I strongly don't believe in the GBA powering some part of the Cube or Nyko using more wires than necessary, I still remain on my "Nyko-cable, ICs - yes" point of view. Those ICs are not very large and I guess with newer techniques Nyko might have smaller or less ones than Nintendo "in the old days", so I think they're in there.
Still, I really want to get and examine one of those by now.
Why Nintendo built electronics into the GBM-Link cable?
I have no idea. I don't think, it's necessary - as you can build those cables without ICs. Still I guess we should be grateful because if it wasn't for those ICs, we might have no GBM-cables with all six wires at all and this whole thread perhaps would have never been written.

The question I am trying to get answered is, what is the PIN out on the game cube. (...)

I hope that helps.
I haven't read all of it but it seems like some of the main questions are answered.
