Excellent, thanks Andy! I might take you up on the offer to switch to a I-PAC VE, but I'd much prefer to keep my IPAC-2 and wire up two extra buttons as you've shown. However, I can't really follow the diagram. The diodes I understand (and have used before), but I've never used a capacitor or a resistor and I don't understand the electrical diagram... Would anybody be kind enough to re-draw the diagram and explain a bit more? If somebody would be so kind to do that, I'd be more than happy to make a nice webpage for it so that this information can be helpful to other newbies as well. |

Best button layout for me. 5 1 6 1 2 3 4 |

Ok, I think I've figured out that diagram, thanks for Andy's help! Thanks again Andy! Now I need to decide which layout to use: 1 2 3 4 4 5 6 or 1 2 3 4 5 6 7 So, regardless of HOW I get it to work (I now have a choice so I don't need to use the Opti-Pac mouse buttons), I am able to fully choose between those two setups :) Which of those layouts would you choose? I plan on playing a lot of fighters, so I'm thinking I would want the top layout. Otherwise my 3 punch buttons and 3 kick buttons wouldn't line up properly. Any thoughts? |

btw, there IS a software only solution for you wire all but the admin buttons (because you will ghosting if you don't). Then for your admin button. Create a dedicated shift button (say '*' for now... and 'z', 'x', 'c' for your bottom 3 buttons on player 1) Next... you hook BOTH the shift key and one of your normal buttons to the admin keys. so when pressing admin button 1, it actually pushes '*' AND 'z' at the same time... do the same for the other 4. Next.. in mame for admin 1, setup by pressing the button (* AND Z) for button 1, press (from keyboard) z, *, *.... This shows up as Z NOT * This will work as long as you arent using the admin buttons while pressing the main buttons... (if you do... then the main buttons will be ignored). This effectively creates a 2x28 matrix.. Other bad notes... it will only work with mame.... Most other emulators wan'ts a dedicated ESC key to exit. I'm not sure if howards wrappers will handle it properly. But you COULD have ESC be one admin button and the shift be another. This will probably take care of all your problems without wiring |
