DolphinBar Light Gun - Crosshairs Limited Movement

  • I just got the DolphinBar Wireless Sensor for my Raspberry Pi 3B+ running retropie.

    The long and short of it is, MAME picks up the gun and movement, but the crosshairs are stuck in about 1/4 of the screen. No matter how much I back up or aim up or down, it never leaves the middle 1/3 of the screen or so.

    I do have the correct mode set (1) and the bar is set to 'bottom' which is where it's located.

    I'm running lr-mame2003, but also tried it with lr-mame 2010 and the same thing happened.

    The only thing I can think of that might be messing it up is that I have a vertical screen instead of the standard horizontal.

    Is there a way to calibrate the x/y coordinates for the DolphinBar?

  • I cant help directly, but I have a similar issue. My LCD monitor is in 'normal' orientation however, with the mayflash wii bar mounted horizontally at the top. My crosshairs are constrained to the bottom left quandrant in mame-2003-plus at least. (pi 3B+, latest official retropie build).

    so no help but fyi you are not alone! I just came onto the forum to search for the same issue

    good luck finding a solution! Everyone here is amazing so hopefully there'll be an answer.
