Out Run in mame with optical wheel = wheel drifts(having over-steer to one side)

[AE35]

Hey all!

I've connected the wheel(optical) on my machine to the PC with an opti-pac.
Everything seems fine the first couple of seconds, but then the steering suddenly
seems to drift in one direction...for example making me have to move the wheel all
the way to the rigth just to go straight. Which make it very difficult to get trhough the
turns

The opti-pac is seen as a mouse, and will move the pointer on the screen in windows.
The problem is the same if there's a real mouse in the PS/2 or not.

I also have other games(SCI, Chase HQ and Pole Position) on the machine, but with the
same problem.

I've spent SOOO much time on this machine, so I REALLY hope someone can help 

I'm SO close now, but problems like these keeps popping up 

Thanks for reading!!

Go into the tab menu then Player controls. scroll down to the dial and paddle settings (since these are usually optical), and set all of the Dec and Inc settings you see to none (select, then hit esc). These are used to simulate optical movement if you are using a joystick, and they will interfere with the optical inputs. Mine usually dove to the left. This should fix games like pole position.

You may never really be happy with games like Outrun. It used a 270 analog wheel, not a 360 optical. You can steer it with an optical wheel, but it won't feel right. Search for 360 or 270 wheels, there have been quite a few threads about it.

Hey Paul!

Thanks for the advice......but it didn't work

The problem is exactly the same as before. Maybe I should just get the fire axe
and get my life back!

Thanks again!

I used my spinner and have pretty high settings. It's workable. Believe it or not, but a guy in a forum comp I'm frequently part of played the game through with a game pad. Anyways, this game is an easy(ier) one in that, while cheaper PC wheels may not have the precision needed, they're 270.

My problem is that I have to hold the wheel 100% to one side just to go straight after some time.
If the wheel is centered, then the car in the game go to the side.

This is on a SCI arcade machine, with the wheel that came with it. (and mame)

Thanks!

EDIT: It seems to do the same on the windows desktop when just moving the
mouse pointer left and right with the wheel. I doesn't return to the same spot
everytime, and the more times I turn the wheel the further the arrow differs from
the first position when the wheel is centered...

If you changed it for all games, go into this game and make sure it is not overwriting the global setting.

edit: Also, check your MAME.ini to make sure dial is set to mouse and mouse is enabled. You might be able to edit this through your front end as well; you can in MALA anyway.

Hey!

Everything is set as you say it should....what AM I going to do.

[Paul Olson]

Which game are you testing? Are pole position  or Super Sprint working right?

So you are saying that the problem is same with the SCI wheel via optipac and a mouse attached to the ps2?  Does the mouse work in Windows or does it drift?   What does the SCI via optipac do in windows?

You do realise that 360deg wheels do not have a 'centre'? I don't see how you can hold the wheel '100% to one side' as they have no limits.

This is pretty normal - there is no calibration with these wheels. All I would say is make sure you have Windows mouse acceleration turned off.

I apologise if I am off the mark but it sounds to me like you are expecting the wheel to behave the same as a 270deg wheel (without the return to centre). This is not the case and while you need to manually 'straighten up', the position of the wheel is highly unlikely to be the same at the 'straight forward' position.

Play Super Sprint and see if it works OK in that...
