Two buttons with same function?
PixelPaul:
I'm working on my first build, a Donkey Kong cabinet. I will be using an Ipac2. Is it possible to have two "jump" buttons, one on either side of the joystick? I'm trying to make the control panel left-handed player friendly (for my wife) who would prefers to use the joystick with her right hand and jump button with her left, which is opposite of the original arcade game control panel layout. I hope this makes sense.

easy peasy, just run a wire from one button to the other. When either button is pressed, it'll jump
PixelPaul:
Cool, thanks for the info!
Hoopz:
You can run the wire from the button to the same input on the Ipac. I do that with a 4 way joy and and 8 way along with a few buttons.

Yep -- I also do the same with my 2nd joystick and buttons 3-6 on my 1 player bartop using a ZD encoder since I wanted to have dual joysticks for robotron and smash TV but the cheap encoder ($10) had only 16 inputs so by doubling up buttons 3-6 with the 2nd joystick it left enough open inputs for the 6 admin buttons I wanted where 16 would not have been enough for 2 joys ( 8 ), 6 buttons, and 6 admin buttons == 20 inputs but by doubling up the 3-6 buttons with the second joystick it uses 4 inputs for those 8 functions - 4 for the other joystick and 2 for buttons 1 and 2 = 10 leaving 6 inputs for admin buttons ( 1 and 2 player credit and start then a Pause and Escape )
Another option for you would be to wire the 2 buttons as separate inputs and then set the MAME setup so that both buttons are seen as the same key (ie both button 2 and 4 are different inputs but when pressed each input sends the same Jump keystroke to the game) -- Then you could also use them as separate buttons for other games if you wanted by changing the MAME setting for those games individually (so for example in some games button 2 and button 4 are both Jump but in other games button 2 is Jump and button 4 is Fire for example) -- Since your encoder has plenty of inputs you could do it that way in case you find you need an extra button rather than having them both wired together.
Really depends on what your needs are but to answer the original question it would be a Yes you can.
