Newbie Switch question
MameFan:
The *ONLY* problem this will give you is the following.
Lets say you have the 4 way turned on. You are pressing right on the 4 way. Then you accidentially press right+down on the 8 way at the same time
The IPAC will see the short between right+ground+down (since even though the ground isn't connected on the other joystick, the crossing of a wire that IS grounded with another one that isn't will, in effect, ground both) and send that combination to Mame.. (same for any other diagonal combination). If you're playing a 4 way game this won't be an issue)
As far as why you need the switch at all... yes, I would agree--if the joysticks are far enough apart, you probably don't need to go thru this work. However I was just answering the question posed, not questioning why it was asked to begin with :)

I never would have caught that.
As far as where to get the switch, SPDT's are available in the automotive section of auto parts stores or Wal-Mart, etc. DPDT's are available from radio shack or on the web from www.digikey.com or www.allelectronics.com or www.mouser.com
