hey dini, i agree with ling as he's been a big help to me in this area. i'm not too sure about the older model ipac mines the newer usb version, but as dumb as it sounds are the wires in the right slots, and connected to the proper cherry switches? also does the ultimarc keymapping program work with that version? any pics?

Is this only in MAME or have you tried in other games as well?

There is a program I found on Byoac called KEYHOOK.EXE that will tell you what keystrokes are being entered as you press your buttons. It was intended for use with mapping out the matrix on a hacked keyboard encoder but can also be used to troubleshoot in situations such as yours. I'm guessing you either have your encoder wired wrong or mame is setup using the wrong keys. It could be that you just have a faulty encoder. The software is located at BYOAC on the interfaces page in the Keyboard Port - Hacking a Keyboard section. Its the one written by someone named David. Or if you don't want to search for it just get it here http://www.arcadecontrols.speedhost.com/KEYHOOK.ZIP . I hope this helps.

hi guys

thanks for your replys:

my buttons are set as follows according to the key test program:

Player 1 Button 1 - A+ left ctrl

Player 1 Button 2 - Q+ LAlt

Player 1 Button 3 - S+ Space

Player 1 Button 4 - W

Player 2 Button 1 - A+ left ctrl

Player 2 Button 2 - Q+ LAlt

Player 2 Button 3 - S+ Space

Player 2 Button 4 - Lshift

seems to be duplicating on each side for some reason or another,do you know how to remedy this problem, my keyboard is connected via ps2 if it makes any difference.

cheers andy

Wow thats pretty strange. It looks to me like some of the wires are either mixed up in your CP or you have a bad JPAC. Also you might try as someone suggested to look over at ultimarc's site to see if anyone else has had this problem. Has this problem just cropped up recently? Is this a new Control panel? Maybe, if it were me, I would unhook player 2's buttons and try the keyhook program again on P1's buttons and see if you still get the duplicating keypresses. So P1 button 1 should be left ctrl when pressed not A+ left ctrl. If the duplicating error gos away then you probably had it wired wrong, if after unhooking player 2's buttons you still get the duplicating error on P1 then I would guess faulty jpac or possibly the jpac programing software has screwed the settings up, though I think this would be unlikely. I hope this helps.
