Hi, I'm stuck.
Well, I built myself this nice 4-player control panel and wired it up using an ipac4. Only two players worked. So I searched the message boards. Then I searched again. Now, I post.
Alright, so here's what I've tried:
1. I know it's not a software problem because p3 & p4 work when a keyboard is plugged in. I've got all the inputs on mame set up correctly.
2. I know it's not the grounds on the wiring because I've got a 4-way wired into the same inputs as first player. The ground connects as follows: p3, then the 4-way, then p4, then p1, then p2, then the ipac4. The 4-way works, so the grounds should be fine.
3. The only other thing I could think of is the wiring inputs with 3 & 4, but what are the odds that they are all wrong?
4. I've tried the KeyThis utility, but when I push the player 3 or 4 buttons/stick nothing registers on the screen.
5. I tried reprogramming the ipac4 using Interacting Panel Designer, WinIPAC, and the other utility for DOS. All gave me jumper errors, but I see no jumper on the ipac. I specified that it was one of the recent ipacs in the options, but nothing seemed to help.
6. I tried the control panel on different computers.
Help, anyone? ???

I know the older ones had a jumper you had to set. I don't see anything about that on Ultimarc's site, so I don't know if the newer ones still have it.
Do you have anything else connected except your controls? When I first hooked mine up, I wired some of my buttons with the kick harness on my jamma board to make it easy to swap back and forth. The jpac would not program when the kick harness was plugged into the board, but programmed fine when I unplugged it.

Hmm, nothing extra connected to the board.
I read on the Ultimarc message boards that the new ones don't have a jumper and that you should be able to program without messing with jumpers.
Thanks anyway. . . anything else I could try? ;D

Have you emailed Andy, at Ultimarc, yet?
That's where I'd start.

That sounds like a plan. I was just making sure it wasn't something stupid I was missing.

I wired up my control panel last night with an I-pac 4 and have the same problem you describe. 2 of player 3's buttons work but the rest of player 3 and all of player 4's inputs don't work. I finished the wiring at 3 in the morning, so I was too tired for trouble shooting, but it appeared all the wiring was correct.
Have you found a solution yet?

I have similar problems. I've got an old style I-Pac and I've tried the jumper settings and programming, P1 button 1,2 and 4 don't work and P1 start won't hold on. They all show as working in WinIpac but don't work in MAME, but all is OK when using a keyboard. I'm now going to look into it again after a late night session last night and not really getting anywhere! If anyone knows if it's a MAME problem please post. I'm using MameWah and DOS Mame under XP.

Is the Ipac plugged into the PS2 port or USB?

did u go into the mame menu, when u load the rom an configure it to work on those controls,,,, open a text file and start hitting buttons on ur cp and that will tell ya if they r working also.
