Wiring quesion...

[BorgWarner]

I have a couple more buttons than I have inputs on my I-Pac, what would happen if I wired two buttons into one input?  They would be buttons that would never be both used for the same game.

If you wired two buttons to the same input, it would be the same function.  They would do the EXACT same thing, you cannot program them differently.

It would return the same keystroke, which is different from performing the same function ... he could change the default controls within MAME (or other emulator, depending) and have the same button return the same keystroke, but do two totally different things in two different games.

Question to BW ... can you solidify your question with an example ?

I have a 5'th joystick for 4-way operation.  I would wire the buttons that go with it to maybe the 4 player buttons, since it is unlikely I would ever use both for the same game.  I would probably do the same with the pinball buttons and the player 3 buttons.  It shouldn't be a problem that they perform the same keystroke, as long as it doesn't cause any other problems. (delay, etc)

If you just want to wire up a 4-way to be Player 1 in games that used a 4-way, just wire them up as you did the Player 1 joystick (e.g. run two wires to the iPac for each of the P1 directions).

Check the following thread -- it may lend some insight ...

I think the real question should be, why do you have more buttons than available inputs?

What controls/buttons do you have on your CP?

4 8-way joysticks - 6 buttons a piece
1 4-way joystick  -  5 buttons (for asteriod configuration)
4 start buttons
4 insert coin buttons
4 trackball buttons
5 pinball buttons
-------------------------
Total = 66 minus the 3 inputs on my trackball =
7 extra buttons

You went over on the buttons for 3 and 4 player, thats why.  Also, the 5 pinball buttons should be wired to button 1-5 with the other ones.

To clarify, there's no need to have 6 buttons for players 3 & 4 as there aren't games that use them.  (I'm pretty sure about this)

There's alway a conditional. . .

There's no need for more than 4 buttons for Player 3 & 4 as there are no ARCADE games that use them.

Different story if you are looking at say SNES or N64 emulation, where you probably want at least 6 and maybe 8 buttons for all 4 players.

That said, USB gamepads are a better option for those games anyway.
