| Question about bridging trackball microswitches for Dreamcast player 3 and 4 |
| (1/3) > >> |

Ok, this is difficult to explain, but I will try my best. I might have an extra Xarcade DIY board, and I want to make a 3rd and 4th player available. Player 4 is no problem because I can give it its own buttons, but player 3 is a problem because I will need the Mouse(trackball microswitches on my control panel. So is it bad to bridge the two keeping the trackball buttons as they are, and then also connecting the grounds also to the DIY board? Or is there a better way to do it, while maintaining the functionality. I would rather keep the trackball buttons acting as they are if possible rather then disconnecting them all together, though it may be unavoidable. Thx in advance. |

There's no reason not to have two buttons wired to the same input (the three player 3 buttons wired to the same mouse 1, mouse 2 and mouse 3 inputs that you have your three trackball buttons wired to--both NO and ground). What ground are you using for the trackball buttons? I would use that ground for the player 3 buttons, not the DIY board's ground. In MAME, you'd map mouse 1, mouse 2 and mouse 3 to player3 buttons 1, 2 and 3. And when you're not in the emulator, you'd have two sets of mouse buttons to play with. |

I don't think I said it correct. The Trackball interface is wired to the 3 buttons(Right click, middle, left Click). I want the SEPERATE DIY board to go to those buttons as well, but they will of course have different commands. So can they be wired at the same time? In that the mouse functions would stay the same wired to the trackball, but the Xarcae DIY board would read the buttons as normal 1,2, and 3(as in I will wire them that way). Will the grounds interfere with each other?? Will this potentially bridge the Dreamcast or any other cosole to the PC??? |

i could be wrong, but i believe wiring 1 button to two different encoders at the same time is a bad idea. That is just asking for trouble. |
