Best way to wire up dual joysticks for player 1?

[fixumdude]

I recently acquired a button top joystick that I would like to add as a second stick for player 1 (I have a 2 player control panel)  I'm using an IPAC 4 player as my encoder.

I've done some searchind and have seen lots of threads on dual joystick games etc. but none on how most people actually physically wire them in the control panel.

Would I wire the 2nd joystick to the player 3 joystick inputs on the IPAC and then configure my crazy climber, etc to use player 3 up/down/left /right for the second player 1 stick?

Am I close or do most people do it totally differently?

Actually, I think I would setup your 2nd 1st player joy as player 3.  That way you only have to redo the 1 player games that require 2 joys to play instead of every 2 player game that uses 1 joy.

Or you could connet both to player one inputs on the ipac.  and save more inputs for later. (not that I have any clue what you would do with that many.)

Witchboard, that's what I meant, but didn't make it clear in my original post (put the 2nd player 1 stick on player 3 of the ipac).

Shape D., That would work it I wanted to use either stick for any game, but I want to use it as a 2nd stick to play dual joystick games like crazy climber, etc. so I don't think that would work for what I want to do.

Sorry, I misread your post.
me no think good.

Would it work to wire it up as another player 2 stick? That way you wouldn't need to reprogram any games would you?

It might be nice to hook up a disconnect switch too -- maybe a quad pole double throw.

This option sounds best to me.  I don't know why I didn't think of it.

Can't say for sure, but I believe Crazy Climber will be set up in MAME the same as Assault/BattleZone - Left stick U-D-L-R, Right Stick U-D-L-R, which doesn't match the defaults so you have to re-program MAME whatever you do.

As I see it, you have 3 ways to go -

Map CC to use the existing P1 and P2 sticks and don't use the top-fire.

Wire the top-fire to P3 inputs and use as planned (probably reprogram P3 on the I-PAC so they don't mirror P2 Buttons 5-8).  This could be useful if you wanted to use this stick for 3-player games as well.

Wire the top-fire to share the P2 joystick inputs.  If you do this, you only need a SPDT (single-pole double throw switch), not quad pole.  Daisy-chain the GROUNDS on each joystick and run the GND wires to the SPDT switch.
