Ok, here's the situation with a dreamcast pad hack. For some reason, when you have the ground of the dreamcast controller hooked up with another interface such as an I-pac, it draws away 5v somehow, and renders your I-pac worthless. But here's what you do, go find a DPDT switch, and hook it up so one way hooks up the controls to the dreamcast grounds, and the other way hooks them up to the I-pac grounds. This is the easiest way to fix this problem that I know of, and is what I'd setup if I wasn't so lazy. -Luke |

Let me ask a question: what's a DPDT switch? If I just have to add one external switch for the ground wire, I think it must not be difficult. Ipac has some advantages over the psx pad hack, since you can program more functions. |

Well... wouldn't a SPDT switch work (if you had one for every button... it's NOT enough to just break the ground.... ) to isolate the DC from the ipac and versa vicE? It's my understanding that's the only way to go. People have hypothesized about using something like one of those old parallel port switchers to switch from DC to IPAC ... and I believe SNaaack even tried one unsuccsefully ---> but I *think* the issue is that his was a "cheapo" one that only cut over the ground and didn't cut over ALL the pins of the parallel port connectors... (i.e. the full isolation we require) I'd be if you found a "real" one of those switchers that didn't "cheat" and switched over a bunch of contacts from one side to the other you'd be in business... Another approach would be to wire up two harness or sets of molex plugs or whatever and switch between them manually... *shrug* Rampy |

yeah, one of those printer switches would work...but it's probably easier and cheaper to use diodes (20 diodes, enough for 2 DC pads, costs around |
