Do you have an analog pedal setup?

[Minwah]

If so, could you tell me how you have your pedals interfaced? Specifically, I am interested in what axis or input you have your pedals wired up to.

I am curious as to whether there is a perfect setup which works well for all games. I seem to be having problems with a few games, and I wonder if anyone else has the same problem.

I use a duel-circuit system which I *think* is probably the best choice, ie an axis (JOY1 Y) for throttle and another axis (JOY2 Y) for brake.  I had a bit of trouble whereby releasing the gas pedal would more often than not, not completely release the gas in the game (the car keeps going). So to get around this, in the windows calibration screen, when told to centre the controller, I would put my foot on the pedal slightly. This basically works in quite a few games, although I have trouble in some games, namely Pole Position/2.

I can tell from the games' test screen that sometimes when I release the pedal, it goes from (a high number) to 00 as it should, but then when the pedal is completely released it 'wraps' to FF or FE.  I am not sure what causes this...could it be my choice of axis, cheating in the calibration screen or a Mame issue?  Funny thing is if I play around with the analog settings, sometimes it ends up working OK (until I quit the game and restart it).

I do remember always having this problem with Pole Position, and never could figure out why. I am determined to sort it out as this is one of the few games where having an analog pedal is pretty much essential to be any good at the game (when I briefly had it working, I got my top score last night).

Note that I am mainly using Mame v0.99, so the input system has no doubt changed since then.  I have some games working ok in this version (eg RoadBlasters), and also Buggy Boy working fine in Mame v0.123.

Any suggestions?

You'd be much better off, by separating the brake pedal onto the stick 2 Z axis. That's how mine is set up. The rason for that is that if they are on the same axis and you hit the brake pedal at the same time as the accelerator they just cancel each other out. That may be the cause of your problem.

Thanks, but they are not on the same axis...one is JOY1 Y, and the other is JOY2 Y - I have them mapped as such and they do not interfere with each other. (Edit: also, I have often disabled the brake pedal just to eliminate this possibility).

Can you tell me what axis your throttle pedal is set to? I was thinking of trying the Z axes, but I had a feeling there was a reason I avoided those.

Also, is there an advantage of either direction...what I mean is pressing the pedal on my setup is 'down' on the Y axis. I wouldn't have thought so but would it be better to swap it round to 'up'?

Do all analog pedal games work fine for you?

I have found a couple of things to try:

1) Move the pots round a bit so they are using higher values (should have remembered to do this).

2) Use Mame v0.113+ with it's new input code.

Buggy Boy works for me in v0.123 with dual analog pedals, so perhaps #2 is worth checking out.

I have done the following which has slightly improved my setup:

1) Moved the throttle to Z-axis.
2) Spun the pots further round while at rest (to give higher values overall).
3) Set Mame's deadzone to 0.0

Now I do not have to do any 'tricking' in calibration, and it seems to work very well for most games.

However I still have problems with Pole Position/2...I made a new topic:
