| SuperBoB2Turbo:
I got my Act Labs TV light gun a couple of days ago. I tried it out with mixed results. This is the first lightgun I've tried with MAME, so I don't know how much of this is already known. First, on calibration. The 'instructions' tell you to move the gun vertically and horizontally across the screen. Well, I was having the same issues some other people on here were having with HORRIBLE calibration. Finally, I figured out that you must go right up to the edge of the screen, but NOT PAST THE EDGE. When I go past the edge, that's when i get the shots off by three inches, like others have mentioned. Do you guys agree with this. If so, Act Labs should really update their instructions. The arrows on the diagram clearly go beyond the edge of the screen, and the written instruction don't clarify one way or another. Secondly, once I have the gun calibrated properly. A disappointingly high number of shots 'misfire'. If I aim off-center, say, 1/3 down and 1/3 over, then i can shoot 20 or 30 shots and they almost all register accurately give or take a quarter inch. BUT, if I aim at the middle of the screen and start firing, I would say as high as 1 in 4 shots register WAY off target, sometimes at the EDGE of the screen. Has anyone else seen this. Is there a way to fix this (I hope)? I didn't expect these guns to be perfect, but firing correctly only 3 out of 4 shots makes most gun games of any skill not worth playing. On a side note, I noticed in the old nintendo gun games like duck hunt and hogans ally, even when the shots would hit as aimed the game seemed to not always register them. Anyone know anything about that? |

I haven't seen that behavior. What TV are you using? I'm running a Toshiba 27A33 I think it's called. My main issue is getting 2 guns to work in MAME. |

I have a pretty nice TV--a 25" Sony WEGA Trinitron using the S-Video input. So, I would hope it's not a compatability issue with the TV. |

(cheap daewoo w/ composite in TV) I can see problems happening if your TV is shiny chrome or silver, or with strong lighting on it (especially from behind), maybe. (Aren't wega's often silver?) --- Quote ---Secondly, once I have the gun calibrated properly. A disappointingly high number of shots 'misfire'.

But it only happens if you shoot the exact middle (either up/down or left/right). If you shoot the exact middle of left/right, for example, the shoot is off by a very small, but random, amount. If you shoot the exact middle of the screen both horizontally and vertically, the shot is off by much more, sometimes to the edge. It shouldn't happen too often, though, because by "exact" I mean the middle 1/257th area. If you want to compile your own, I can tell you what to do to fix this problem. However, I'll also tell you problems introduced with it, too. --- Quote ---On a side note, I noticed in the old nintendo gun games like duck hunt and hogans ally, even when the shots would hit as aimed the game seemed to not always register them.

My Sony is silver, so that's probably what's happening with the calibration. Guess it's time to install a bezel :) You're right about the exact center thing. When I'm shooting at the center I'm aiming at the default reticle that MAME puts on which is in the exact center. And since I'm such a good shot ;D I probably am hitting the center a lot ;) I would be interested in hearing about the bug fix. Thanks for the help! |
