Hacked DreamCast Pad Problem! (Keywiz Max)

OK.  That sounds great.  But, really, I have no idea how that would look or how to go about doing it.  Is there a tutorial around somewhere?

Just wiriing the CP was a stretch for me!

I'm sure there are some tutorials, but I don't know of any offhand.

Basically it comes down to the pinout of whatever connector you decide to use.  Let's say you use DB25 connectors.... You'd have the pinout for that connector.  Each pin would correspond to one control... so pin1 might be joystick left or something.  You'd wire your Keywiz joystick left to pin 1.  Wire up the Dreamcast joy left to pin1 of another connector.  Do that for every control and you'll have 2 identical connectors with the same pinouts... one for mame and one for dreamcast.

Now you plug those two into a switchbox.  You then have one connector come OUT of the box and to your actual controls.... just mimic the same pinout (pin1 is joy left, etc), and all you'll have to do is turn the switch from A to B.  I hope that makes sense.


EDIT: Take a look at this pic: http://www.connecttech.net/product_info.php?products_id=1600

You'd have the Keywiz on the bottom right, Dreamcast on the bottom left, and controls on top.  And out of each connector you'd have bare wires (not another DB25) that would go straight to either the keywiz/hacked pad/or control.
So you'll have wired up THREE connectors... one for the Keywiz, one for the Dreamcast, and one to connect to the actual controls.

Ok!  I think I'm starting to get the picture.  I'll read these posts again once I get home in order to try to fully understand!

Would a place like Radio Shack or Cirtcuit City have a switch box/connector for this king of thing?  Even seeing photos of these would probably help.

Thanks!

Hey again!

Thanks again for your help.  I think I'm starting to understand this.

Here's my question now... If I decide to go for Molex connections..  Ideally I'd use 2.  1 for each player.  The problem is.. is that I have 16 inputs on player 1, and 17 Inputs on the Player 2 side.  Are there molex  connectors that have more than 15 inputs?  Would I be better off using a db25 connection.. and would it work exactly the same way?

So.. just to anchor this.  I would need one female for each of the players controls.  2 Males for each dreamcast joystick.  and 2 males for the Keywiz.

Does that sound about right?

thanks!
