LS30 Rotary Joysticks

<< < (2/2)

jerryjanis:
I'm using Druin's interface.

Hmmm...  Setting each direction to a different direction and editing mame to handle it...  That would fix my problem with the analog settings...

But I still think you're nuts, when druin's interface is available.

Is there any detailed information out there about the speed/sensitivity settings associated with analog controls in MAME?  I've been playing around with those settings, but I'm just making shots in the dark.  It would be a lot easier if I had some idea of what each setting (speed/sensitivity) is actually doing.

The Key/joy speed setting is designed set how fast an analog value changes if you input data with a digital device, like with a keyboard or d-pad (but also effects analog input devices some how).  Sensitively adjusts a multiplier for analog devices to set how much a value changes compared to how much the spinner/trackball was turned, and does not effect digital devices inputs to the same port.

For trackball, mouse and spinner devices, this depends on the system settings and which brand & model trackball/mouse/spinner you are using, so varies from system to system.

But for Ikari Warriors and keyboard/d-pad inputs (which the rotatary joysticks are), I agree that most should use about the same values.  I think I saw some numbers somewhere, but can't remember where.  Anybody else?


--- Quote ---I've gotten Ikari Warriors to maybe 95% correctness, but it it's gotta be perfect, right?  Or else what's the point?

Agree!

The rotary can be thought of as either: 12 different switches, or as a analog input with 12 different possible vaules.  With the limits of the PC keyboard, I think mame went with the latter, since spinner support was already there, and game play would be easier with a spinner than 12 different keys.  So mame's default speed/sensitivity is set to close to what most spinners would need.  Again, I don't remember where to find approximate settings values for keyboards, but I think I saw a page with them a while ago.s

First off, the originals were mounted to a metal control panel, so that's your height problem.  You could attach some sheet metal to the top of the panel and cut a hole beneath for the joystick to stick through.  (Just an idea!!!)

Frobozz:
How / why is it handled like an analog control?  I thought it behaved like a pair of buttons if you got 12-switch sticks and Druin's card.  

I guess, if it did behave like analog, I'd set the sensitivity very high and the key speed very low.  Does this seem similar to your settings?
