Title: Problems with Dual Joystick Games
Post by: campbelldave on July 09, 2007, 10:21:18 pm

Hi,

Sorry if the following has been answered.  I searched on the board and could not find the same problem.

I recently built a 4 player CP (Happ Supers for players 3/4 and 2 Happ Rotary for players 1/2) with an extra joystick (a Happ Super) to be used so player 1 could play Karate Champ, Crazy Climber, Smash TV and Robotron.  I am using an IPAC4.  Yes, the CP is gigantic, but I wanted something that all of my friends could use.

I switched the controls to map properly for the 2nd joystick for those games.

When I try and use the joysticks on any of those games, it is as if something is sticking or it's reading a different signal that what I am entering with the joystick.  If I use the keyboard and use the keys that I mapped to, I can play the game (not very well) and everything works OK.

I checked the 2 joysticks in notepad and nothing is sticking there and they are entering the proper keystrokes.

Do both joysticks need to be set up to be 4 way only to work with those games?

Any help you could give me would be greatly appreciated.  Thanks

I'd really like to know if this works too.

I am about to start building my first cab and definately want the 4 sticks for Karate Champ, SmashTV etc.

I assume I need the iPac4 anyway to support the extra sticks, or will the iPac2 work? (not interested in having '4 players' as such, just 2 players, 2 sticks each).

Thanks!

Karate Champ has to have 4-ways, or the character will stick.
Crazy Climber works best with 8-ways, but will play with 4-ways.
Robotron and Smash TV both need 8-ways, otherwise you wouldn't be able to shoot diagonally.

If you only want a 2 player setup you could use 2 joysticks each and and still get away with just the ipac 2 by sharing the connections from the main buttons to your secondary joysticks.

Sounds like either a wiring problem or maybe you are accidentally activating your IPAC 'shift' button?
