Turbo Twist 2 & Trackball won't play nice!
(1/7) > >>
mybrainhurtz:
I just received my 3" happ trackball and TT2 and am working on tweaking them in mame (using a custom compiled 121 to add highscore support).

I hooked the x and y axis to the trackball(because I want it to double as a mouse) and the z-axis to the spinner, but I found that even if I set the sensitivity of the wheel in windows to "1 line" and the analog sensitivity in mame to 1% it still was way too sensitive and was getting bad backspin (I was testing it in Tempest).

Are there any other registry tweaks or programs that I can download to have more control over the sensitivity of the mouse wheel/z-axis?

I have tried the spinner on the x axis, and I can adjust the sensitivity in mame to get it to work perfect. I haven't tried the trackball on the y and z axis, but I imagine that it is going to be a pain in the butt to make the horizontal and vertical motion of the trackball feel even with the large sensitivity difference between the axis...and I wont be able to use it as a mouse in windows set up this way.

What do you guys suggest I do? I did not purchase an opti-wiz when I ordered the TT2 because I read here that you could hook a trackball up to it with no problems.

Thanks for your infinite knowledge guys!!

You can try the stuff in this thread. I've been having issues myself. I don't know if I have a wire loose now or what but it's horrible at the moment. I haven't been that worried about it because I'm building a new cp soon. Good luck and keep us updated.

Did you try using a different axis for the spinner?  Sometimes the z axis has sensitivity problems.

Just to clarify, the problem is with the way the OS deals with the Z-Axis.  At one time, the Z-axis was being divided down with the official MAME distributions in order to allow the Z to behave like the X and Y.  But I'm not so sure this is still being implemented.  Something tells me it's been changed back, based on all the comments about the Z-axis lately.

If the Z-axis is crazy sensitive when compared against the X and Y axes, then the MAME code is probably no longer doing what it used to.  Try using a version prior to the addition of the new input system.

Thanks for the replies... here is what I know so far...


* If I put the spinner on x or y, it works fine.
* If I use an older version of mame(ex. v105) it works fine.
The next thing that I need to do is move forward in versions of mame until I find which one implemented the input change. I would simply run version 105 all the time, but after doing some random sampling in 105, I found that many games don't run nearly as good as they do with 122.

why do they have to keep taking useful stuff out of mame... highscores... z-axis... sigh...
(I know they have good reasons, im just frustrated haha)

So, what are my options? I don't suppose there is an easy fix such as a diff out there that I can compile with the newest version of mame to slow down that pesky z-axis is there?

Probably not...  :(

I don't want to run a different OS, since I plan on running a few windows games from my cab.

I installed Microsoft's Intellipoint drivers to try to get more control over the scroll wheel speed, but  even with the slider the whole way to slow, it still makes no difference.

I guess the real easy fix is to go out and buy an opti-wiz, but I thought I was done buying controls... argh! :censored:

hmm... what about hacking a mouse for my trackball... would I have issues with backspin?

Well, this started out as a quick update and turned into a frustrated rant... sorry about that :) LMK if you guys have any other suggestions for me... I am hoping that there's some way around this...

Thanks!
