I have a Saitek X-52 joystick which has a pinkie switch located near the base at the front:
A while back I was going mad trying to program the stick's software to make the pinkie switch behave more like the M1 gunner's palm switch. IOW, I wanted the pinkie switch to be required to be pressed for the stick to work. And if I let go of it, I wanted that to zero the lead. I just couldn't figure it out.
Well, a few days ago it hit me. Why not just change the control options in Steel Beasts to "control handle"? :c: And that did it. Now the pinkie switch operates the same way the M1's palm switch does. (At least as I understand it.)
Some might say it's a minor difference, but to me it's pretty neat. I don't know if there are a lot of joysticks out there with similar buttons, but I thought I'd just throw this out there.
Note: The pinkie switch is mapped through the stick's software to emulate the keyboard's "P" key.
