Summary |
01861: Setting of Player1Button1 for Lightgun is not working correctly |
|
Description |
According to BYOACwiki, setting the player 1 button 1 (P1B1) (trigger fire) for a lightgun should produce this result:
["It shows "Mouse 4 Button 1"]
Setting button one with the lightgun pointed at the screen does not produce that result. [See "additonal information" section below]
It will produce that result only if the lightgun is fired offscreen during the set up for P1B1. Doing so sets the P1B1 so that during game play it updates the cursor (moves it to the pointed-at location) but does not fire the weapon. In fact, this effects also produces the off-screen reload on games which allow it, even though the cursor is clearly and accurately updated on screen.
To set P1B1 to actually fire the weapon in addition to updating the cursor, the light gun must be pointed at the screen when setting P1B1. When doing this, the result is not "Mouse 4 Button 1", but instead produces a formula, which varies depending upon where on the screen you pointed the lightgun when setting P1B1. By formula I am not referring to accidently setting multiple keystrokes which will be accepted as P1B1, but an actual formula based upon the x and y coordinates of the mouse (lightgun). This formula will allow the lightgun to work properly only on specific portions of the screen. For example, the gun may fire at all targets on the left side of the screen (the side for which the forumla provides the proper result). For the right side of the screen it will only update the cursor (move it to the selected position), but not fire the weapon, and if allowed, will also reload as if fired off screen.
This essentially renders the lightgun ineffective for all lightgun games. |

Steps To Reproduce |
Is 100% reproducable on all light gun games on my system by following the lightgun set up instructions provided by BYOACwiki...

Additional Information |
I have scoured forums and have seen many players also suffering this problem, with no working solutions posted.
Mame.ini is configured to allow the mouse, to allow multiple mice, to allow off-screen reload, to refresh rate 60, to auto resolution, and the gun is calibrated for the specific lightgun game being attempted using the calibration switch on the lightgun itself. Calibration is effective and accurate (meaning the cursor updates to exactly where the lightgun is pointed). Holding 9 and f2 to calibrate the game has no additional effect.
Windows XP desktop screen resolution is 1024x768, in case that is in any way relevant.
The lightgun used is ACT Blue lightgun, set for Player 1
