P2 button 5 & 6 not working

[krick]

I can't seem to get player 2's buttons 5 & 6 working on my machine.  When I play any of the CAPCOM fighters as the second player, buttons 5 & 6 are dead.

At first, I thought that the problem was my J-PAC or my wiring but if I open notepad in windows and hit each of player 2's buttons in order, it types:

asqwik

So the problem isn't in my wiring or the J-PAC.

Any ideas where I should look next?  This is frustrating.

Have you tried setting them up in mame?

I was having this "problem" before too and it so pissed me off, and I nearly made another hole in the wall (with my head) when I found out the "problem"/solution.  You just need to configure the two buttons  in MAME.  For some reason, by default (or whatever) those 2 buttons are not assigned automatically (anymore?).

He is 100% correct.

Out of the box, MAME is configured for Player 1 buttons 1-10 and Player 2 buttons 1-4, anything beyond this, you have to set up yourself.

Thanks all.  Got it working now.

I made an (incorrect) assumption because my J-PAC had "MAME default" settings that included 6 buttons for player 2.

The J-PAC does have default setting for these buttons. The problem is that MAME does'nt. Why, I know not. This is probably the number one support question for I-PAC / J-PAC.
I think I'll try to lean on the MAME devs to add these keys into the default setup. It would be really good if they were to use the keycodes I chose for the I-PAC defaults...would save a lot of support emails.

Actually, I thought there might be a problem because the I-PAC defaults for P2 Buttons 5 thru 8 are the MAME defaults for P3 joystick movement, but since there are no 3 player or 4-player simultaneous arcade games with more than 4 buttons, this actually doesn't cause any problems.
