Ipac 4 Default Keycode Problems

Pages: (1/5) > >>

xer0s:

I have a 4 player cabinet with 6 buttons on each player.  I noticed this problem when I was playing TMNT on Mame.  When I press buttons 5 & 6 for player 2, it moves player 3 up & down.  I realize 6 buttons aren't needed for TMNT and most other games, but it still shouldn't be doing this.  I went to a game that requires at least 5 buttons (MK3), and tested out button 5 on player 2 and it didn't work.

So I checked the default keycodes at http://www.ultimarc.com/ipac2.html and found that input 2 SW 5 and 2 SW 6 are mapped with the same keys as 3 UP and 3 DOWN.  Does this not interfere with games that require 3 or 4 players and 5 or 6 buttons?

I have emulators for Atari, Nes, Snes, Sega, and of course Mame. 

What's the best way of going about this?

Interesting.  Maybe this is set up this way because it is defaulted for MAME, and you should not have a reason to be using the 5&6 buttons when playing a game that has more than two players.

In any case, I would just use Ultimarc's software reprogram the controller.  Shouldn't take you too long to figure out, it is fairly straight forward with decent documentation.  You just need to find a couple more keys to use on the keyboard for player 3's up and down.  Then make the appropriate changes in the input settings of your emulators.

Alright, but why does button 5 & 6 not work when I'm playing a two player only game?

yotsuya:

By default, MAME doesn't map buttons 5 and 6 for player two.

PL1:

There are actually two more overlapping keys -- both Player 2 Button 5-8 and Player 3 directional default keys use I, K, J, and L.

Pretty sure the overlap started with Andy choosing default buttons for the IPac2 which became accepted as pseudo-defaults.

Just reprogram the IPac to "deconflict" the overlaps.
