I-Pac question: 28 or 56?
« on: November 19, 2002, 09:36:57 am »
Hello all!

I am planning out my first MAME cabinet, and am already confused on one front.  Which I-Pac do I need?  I want to make a 2 player cabinet... with the following:

First player button
First player coin
Second player button
Second player coin

6 buttons for player 1
6 buttons for plater 2

2 - 8 way joysticks (how many inputs does this require?)
1 - 4 way joystick (how many inputs does this require?)

I assume that the buttons would require 16 inputs, leaving me 12 more.  How many do the joysticks take?  Are six buttons good per player?

Thanks.
Shawn

Why don't you count it ? Just in case you can't count, take a look at what I got for you .

First player button         1
First player coin             1
Second player button    1
Second player coin        1

6 buttons for player 1    6
6 buttons for plater 2     6

2 - 8 way joysticks      4 each = 8
1 - 4 way joystick        4

So the total is 28 and that would be IPAC2 not IPAC4

Thenasty-

I guess my confusion was that I did not know that an 8-way controller took 4 inputs.  I thought that it took 4 or 8, but I was not sure.  Thanks for your help.  I can count but I was not sure what to add.

Do four way joysticks only require 2 inputs, or do they also require 4 like 8-way?

Thanks.
Shawn

as my reply above, 4-way or 8-way still takes 4 inputs.
The 8-way (up.down.right,left) then where the hell to make it 8 ? well when you push the joystick diagonally, UPandRIGHT this trigger the diagonal that make it move diagonally. so, you have 4 diagonals and the other 4.

You could also save yourself 4 inputs and wire the 4 way into the same inputs as the player one 8 way. That would free up a few buttons in case you wanted a dedicated escape or something... You just have to remember you cant bump the 8 way while you're playing 4 way games (or vice versa)  ::)
If you build a frankenpanel, chances are I don't care for you as a person.

Brax,

I was just about to say the same thing.  I have a HotRod SE and have hacked all kinds of contraptions to it.  I currently have a Midway coinbox wired to the 3 and 4 keys inside of the HotRod, and I aqquired a 4 way Pac-Man joystick that I wired to the left control pannel.  Works great in 4 way games, but have not mounted it yet.  I still have to hold it in my hand like the Atari 2600 days.    ;D

Works great though.  I am in the process of building a Mame cab out of a PLaychoice 10 machine, with dual monitors.  Until then, I have a "Poor Mans Mame Cab" with a HotRod SE, a KDS 19" monitor that is vertical more than horizantal, a coin box screwed in to the fron side of my bookcase connected to the HOtRod, and the 4 Way PacMan stick for the older games.

What brax said, wire the 4way to the same input at the player 1 8way, it's the same inputs anyway.  that will leave you with extra buttons if you want a dedicated button for pause, quit, or whatever.  Check out my cabinet, all that is wired to the IPAC2 (there was no IPAC4 when I got mine).
The buttons on the shefl, the left group of 4 are start and coin buttons.  The middle three, quit, power, pause.
The spinner and trackball are USB...


To word it another way than TheNasty, a 4way joystick bocks the joystick from moving tot he diagnals.  And 8way doesn't, hence eight directions then.  But it still just has 4 buttons, it know the diagonal when the up and left button are pushed, etc...
