Check all your grounds are good and connected. Had a wired issue with mine and was a ground wire not right on cabinet.
Unofficial Pi Position Q&A & Support Thread
- Thread starter Glitch
- Start date
I've not installed my board but wanted some feedback on using the board to run other games. My original PP2 boards are fine. I wanted this board along with the switcher so as to run some other driving games in the PP2 cab as essentially a driving multi cab with a gas and brake (pilfered from a cockpit version). Has anyone done this successfully yet? What games are working and is there a front end that can be installed with a menu?
here is a software update that fixes the volume , scoring and full speed issue
as of now the only remaining issue is that damn screech sound

Here is a compressed zip image of that update. It is about 700 mb instead of 15 GB though you will have to unzip it yourself.

I'm experiencing practically the same issue with my G07 not syncing with my PiPosition. Confirmed sync is composited and have continuity on the sync line from the PCB harness to the G07 sync header. I don't have an original PP board to compare but a 60n1 syncs perfectly on the same monitor and the issue occurs connecting the PiPosition to a different G07 that works perfect on a Millipede. B+ measures spot-on at 120v. The best I can dial it in is a very narrow position on the HorizFreq pot to get a wobbly/shaky picture (back and forth not just scrolling in the same direction). Reflowed all G07 headers, replaced HorizFreq pot and tried the latest SD card image Jason posted in this thread and issue persists.
Is there a video setting in AdvMAME I could try adjusting for this or are we looking at some other kind of update?

Gav, did you ever figure this out? I'm having the exact same problem. Game runs, but no inputs (coin, steering, gas, or gear shift).

Finally getting to my pi position project. Currently I can not get monitor to sync. I have tried two different monitors (a g07 and a wells k7000 13 monitor). I even tried using one of those chinese cga to vga converters with a vga monitor. None are able to sync properly. If I use positive sync. The horizontal is fine, but it will not lock in vertically. If I use negative sync, I can get a vertical lock, but horizontal is messed up (I have a locked picture, but its unstable, not proper raster and even messes up some colors. I have tried pretty much all combinations of using both HS VS + and - .
I do have sound and controls, which is good. Now if I can just get the picture to work.
I do have an o-scope and I am pretty good with electronics, if anyone knows how I can back trace to check and see if I am getting proper signals from the pi position. The composite sync comes from the 74LS86AN chip . Is there a schematic available anywhere so I can trace this down? Also if anyone knows where the two syncs are before they are combined, I could even just run them to their individual sync connections.
Also if anyone has run into these problems and has some troubleshooting tips I would greatly appreciate it.
thanks in advance.

ps. Also could it be possible that its a software configuration problem that is setting the wrong mode for the arcade monitor??

I just figured out a piece of the puzzle. I went back to the original software and the picture syncs up perfectly. I had never tried the original version since I didn't get to my pole project until recently. So at this point, I have the original software with perfect picture, but no sound or controls (and I imagine dip switch problems) and an updated version with sound, controls , but bad sync. I will try re-downloading the new versions and see what happens.
So I guess what I am trying to say is that sync issues can be a software configuration problem.

I now have a working pi position. I used the compressed image above in the thread by linx310 (the image that is 640mb).
I don't know what was wrong with my previous version (it should have been the same). Also I don't know why the original version that shipped with the pi position did not have sound or controls, but I don't plan on looking into it.
later,
mickey

does anyone know the default "arcpi" login/pass? i'm trying to play around with a few settings but not sure this is documented. thx!

Has anyone got the under voltage message. I have a switching power supply and I have double checked the voltage is 5. There is a long message associated with the under voltage but I am reluctant to keep it plugged in and trouble shoot in case it causes some type of damage. Does anyone have a photo of the card hooked up. so I can double check my connection orientation??
The games still boots up but once I press the gas pedal it goes back to the error message and starts over "reboots"

Jason, can you check on my order? Been waiting a good while for mine.

Below is the actual message. Again it boots past this to the welcome screen attract mode minus sound. Once I step on gas pedal it reboots this message reappears and back to attract mode.
Anybody have any advice on where to start? The game works with the original boards for about two minutes before it resets so I know sound, gas, steering etc work.

Hello everyone!
Let me start by saying thank you to @ArcadeJason for all the hard work you put into making such a badass "Pi Position" and thank you @Glitch for adding this support thread.
As for me I was fairly lucky as I unpacked the Pi Position, plugged the board in and all I had to do was turn the reverse ON for Pedal 1 and set the proper DIP SWITCH settings so I could reach 244.
The only issue I'm having is the gas pedal has a huge delayed response when I decelerate.
For example when I floor it, I can get up the top speed (244) as expected but if I let off the gas completely it takes at least 2-3 seconds before it starts to decelerate and when it does, it decelerate at the expected rate.
I did was update to the image file posted by @ArcadeJason on Apr 27th.
Results:
Skid sound still off but again I think thats solved in another thread. Unfortunately the deceleration issue remains
Shifting and steering work perfect.
Any idea on how to address this? Is there some kind of sensitivity setting in MAME for this?

This sounds like some kind of power issue with your cab and not your boards or the PiPosition.
I would check that thoroughly before plugging the boards back in. You could damage them.
Sent you a message in messengerhere is a software update that fixes the volume , scoring and full speed issue

Ive got a problem with the image on my Pi Position on a G07. For reference is a picture with the TPG. I cant get it to go horizontally enough, so theres black bars on either side. Its got a slight left and right jitter I cant seem to make go away. I can stretch it vertically enough but when I do it how far it needs to be, it makes the image look kinda strange. Almost like its adding gaps between the pixels. On my harness I have a male and female spade connector, but I dont think these plug into G07s.
Mine is not updated to the latest software version, if that makes a difference. Waiting on a microsd reader

One of the threads here has information on adjusting the screen via the config file on the card, but you'll need that card reader. I would also upgrade to the latest version, that seemed to fix a few issues.
Do you happen to know the dip settings needed for the 244? The only 2 issues I am having are not reaching 244 and always having to apply the reverse setting for the pedal (auto-accels if I do not change the setting). Know anything about how to get the reverse setting to be saved so it does not have to be reapplied each time the game is powered or switched? Thanks in advance.Hello everyone!

If you check the first page of this thread you will see a post by @Glitch that has the dip switch settings.

For monitor adjustment, change the following settings in your config.txt file, and fine-tune with the monitor controls.
Code:
# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
overscan_left=40
overscan_right=40
overscan_top=40
overscan_bottom=40
