A unofficial relase is out containing some improvements on the lightgun, they are:
- Calibration screen with instructions, and calibration stored per port and lightgun
- Improved lightgun in games: It will not default to the center of the screen if not "seen"; tweaked the lightgun "processing" so it will hit almost every time(even when pointed in a black area), and will reload if you shoot offscreen (at least on those games that have support for it by the mame core)
- Multiple lightgun support
- Tweaks for compatibility (there where some Joytech Sharp Shooters that had the white and black buttons half-pressed internally, had to increase threshold for button pressing)
