One button to J-PAC & Opti-PAC

[lettuce]

I want to have a mouse button wired to one of my service buttons on my CP, how do i got about wiring a J-PAC and Opti-PAC up to use the same button. I did have 2 wires connected to the NO terminal on a button, with 1 wire going to the J-PAC and the other wire going to the Left Button terminal on the Opti-PAC, but this didnt work and caused a few conflicts, so im at a loss. Can anybody help?

The basic answer is you don't want the same button activating two inputs.

If you are mainly using MAME, you can wire the button to the left Opti-Pac terminal (only) and set MAME up to use the left mouse button for that input.

If you need to use it for other games, I think there is a program called keymouse (?) that will let you send a keystroke when you click the mouse button.

Alternately, I don't know if there's a way to wire the button to the J-PAC and use software to send a mouse-click when the key is pressed, possibly with UltraKeyBoard or AutoHotKey.

Well i want the same button to be used as the left mouse button for windows, and then it would be a service button in Mame i.e, pause, menu etc. I was under the impression that it was ok to have the J-PAC and Opti-PAC wired to the same button??

I would think you could wire it to both inputs and the only problem would be that pressing the button would send BOTH and keypress and a mouse-click (which could be bad for some games), but I think others have said it causes problems.  At this point, you might E-mail Andy about it and post back what he replies.
