Jollywest:
Try using F2 in game to access the original game test menu, a lot of mame gun games have a gun calibration menu in it for better accuracy.

BadMouth:
This is like mapping positional guns. You need to have a good understanding of all the analog settings in MAME as well as understand that you have 3 layers of calibration to deal with; windows, mame interface, game service menu.

from an old post about analog guns:

1. Calibrate the positional gun in windows by pointing it along the edges of the screen.
2. In mame.ini set the dead zone to zero.
3. In mame.ini set the saturation to 1 (100%)
4. Calibrate the gun in the game's service menu
5. Adjust the sensetivity under analogue controls in MAME's in-game menu until the crosshairs don't lag behind the gun movement.
(there is only ONE sensetivity setting, ignore all settings that include the word DIGITAL)

or just reverse the leads for the x-axis on the KADE. ;)

twistedsymphony:
there's only 1 wire for the X-Axis... nothing to reverse :lol

Not all games have gun calibration in MAME. the first game I tested was Lethal Enforcers... checked the test menu... no calibration :-/

if the analog output can be mapped correctly outside of the game then any in-game calibration shouldn't be needed since MAME is just sending screen coordinates into the game.

A better solution might be to have a wrapper that re-interprets the analog data as a pointing device and allows for it's own calibration. that would theoretically remove any need for calibration within the emulators themselves.

burn_654:
What about the calibration features in the windows gamepad control panel? could that be of some use?

It's been a while since I've had to use it but for analog joysticks you used to be able to calibrate there by moving the joystick to its extremities.

This is exciting stuff to see happening!

Nope, that's not how it works. You still have to calibrate each and every solitary gun game. This sets the min and max values for the emulated hardware, which default to 0 on most games. A few true lightgun games don't have a calibration option as you've discovered, but other than that... yeah you've got some work ahead of you.

Badmouth's list is correct. Calibrate the "joystick" in windows control panel first and go from there.

I would suggest starting with games that used analog guns, like Terminator 2. That'll give you a good idea if it's a hardware thing or what.
