Open up an old pad and hack the buttons directly to the pads. That's about the only way it will work. I suggest an off-brand controller, they tend to be easier to work with.

RetroZone has some stuff you can buy if you don't want to hack anything.

If I understand your question, you want to be able to switch between your NES and computer on the fly wiht little to no incovenience, hopefully only pressing a button or something of that nature.  IF so, you could take a couple of different routs.  If you used a DB-25 swtichbox, with 1 input and two outputs witha switch to determine which output was active, you could then run one set to your encoder and the other to hacked NES pads.  ALternatively, you could use molex connectors and just swap the connection between the NES and computer.  Finally, there was a diagram floating around here for simultaneous connection between DC controls and an IPAC, if your using a similar setup you could probably do that too.  It had to do with using diodes to control the flow or something like that...I honestly dont remember much about it because I went with molex connectors

yeah basically i want to run acutally systems with my computer and ipac without changing wires all the way.  for right now i just want to use my NES

i was thinkin of routing two wires from buttons and joysticks  one for ipac and other to nes pad.

what do you guys think?

If so, look up that dreamcast wiring diagram I was talking about, because you'll need diodes probably.

Those are normal pads hacked to go into USB. They will not let you interface controls into the NES easily (actually, at all).
