Hey guys, I need some help troubleshooting an issue with my system. Help! First, here's the specs: * IPAC4 (connected via USB port) * Player1 + Player2 = Ultimarc 360s (analog) * Player3 + Player4 = Sanwa JLWs (keyboard emulated connected to IPAC4) * Admin buttons (connected to IPAC4) The symptoms: * Player1 + Player2 play all games perfectly in MAME. * Player3 + Player4 have odd ghosting and/or unresponsive behavior in 4-player games. For instance in Gauntlet II; Players 3 and 4 try to move, and sometimes the character moves, sometimes the character keeps repeating their shots, and usually the character doesn't do anything at all. It's like there's huge delays and repeating keystrokes. * When I play a 4-player game (like Gauntlet II), the admin buttons also get unresponsive. They seem to work fine in 2-player games though. Troubleshooting I've done: * Disabled sticky keys. * Checked for USB Legacy Support setting in BIOS. It is not part of my BIOS. * Replaced the "Q" and "S" keys, mapping them to other keys. Also replaced the "Alt" and "Shift" keys with other keys. Still no improvement. * Checked the key strokes in the WinIPAC software. All keys register correctly with the button presses/joystick movements. There are no delays here. * Checked the key strokes in the Keyboard properties part of the WinXP control panel. Make sure it allows the fastest repeat keypress. No change. * Checked Notepad to make sure key presses are working. The correct letters/numbers appear in Notepad without any delays. * Disabled out all the non-essential settings in MAME (like Service1 button mappings, etc), just to avoid any conflicts. There should be no button conflicts in MAME now. * Enabled Multikeyboard setting (set from 0 to 1) in MAME.ini. Still having the problem. I do have a lot of gatherings at my house, including my bachelor party this Saturday! So it's pretty important for me to get all 4 players working correctly. Any help that people can provide is appreciated! :) |

I've read in old posts that keyboard hacks can cause this, but not IPACs. I wonder if this is a MAME configuration issue (since it seems to happen only in MAME), or a wiring problem with those joysticks. Just to be sure, I'll ask this- for 8 way mapping, would MAME be configured something like this? P3 Up: Key I P3 Down: Key K P3 Left: Key J P3 Right: Key L P3 Up/Left: Key I and Key J P3 Up/Right: Key I and Key L P3 Down/Left: Key K and Key J P3 Down/Right: Key K and Key L P3 Left/Left: Key J and Key J P3 Right/Right: Key L and Key L P3 Left/Right: Key J and Key L P3 Right/Left: Key L and Key J Or could the Left/Left etc be confusing the IPAC? |

I don't think the combos of I and J for up left etc are needed just up down left and right for the ipac. |
