Games that used mechanical guns wouldn't. |

At least it doesn't for me with WinGun. |

About the J-Pac: I do not have a J-Pac myself so I need more information about your setup (connections, monitor etc.) before I can help you. Anyway I recommend you to use a separate circuit connected between your ArcadeVGA card and your J-Pac for connecting the gun. There are so many ways to connect things together. This is why I make my circuit so it should be connected directly to the graphics card via rgb, s-vhs or composite so that further connections can vary except from scanconverters etc. I will try to connect to the ArcadeVGA as soon as I can. About the screen flash: Yes, it is easy to make the screen flash via rgb-signals on arcademonitors, scart-tvs and pc-monitors. I do not think the TIMING of the flash should be controlled by software but by hardware timed to the sync signals. TRIGGERING the flash must be controlled by software via (as you say) the parallel or serial port. Many people use s-vhs or composite for connection to their TV. I would really like to use a sync-separator to make things a little easier with screen-flashing on these although this increases the component-costs. I could of course make two versions, one for vga-signal and one for video signal. What do you think ??? |

@zeropoint You can try to do anything you want but, there is one thing I learned writing the driver, you will never be able to cover all the ppl's configurations :D When I start writing it I thought about the RGB connection and this is the way I meant it to work. I am happy that ppl have tested many different combibations. Some connections had less results than other ending up in driver hackin and very dirty things to make it work (in reality some ppl discovered it is just a connection issue). So, what I want to say, you could even add a LM1881 to separate syncs from composite out and so on .. but tomorrow there will be someone who will say "How do I connect it to my satellite antenna?" :D The rigth way is starting with the simplest connection (hopefully the one you can test and work on) and after that you "could" try to satisfy the more different request you can. About the HW : I don't think you should hook the sync. It would need a microcontroller for that but we can do without. Just put white level on the VGA for a couple o millisecs. If you handle to show me something in HW to handle the flash I can try to modify the driver to handle it. I can set the TX HI on the serial port when you pull the trigger and read coordinates some millisecs after. |

I know what you mean ! Many people ask things before they think things through and I probably do that myself some times !? That |
