I just finished installing one for a buddy and I had it in my garage and I noticed it change games one time when I touched the coin door and had some static electricity. Never had it change games except that one time.

Have you tried changing the test button that is used to switch games? Not saying this is my issue but I opened the coin door and the coin mech bumped the counter and boom reset. Then I barely grazed the button and rest. I and going to change that and give it a try.No I never figured it out. I'm going to try to hook a scope up to it and figure out what it's doing when it resets, it's pretty frustrating. Glad to hear at least one other person on the planet has the same issue. I've probably spent 20 hours trying to figure it out, but I don't really know what I'm doing, if I spent that same 20 hours working on the original pcb's I could have fixed 3 or 4 sets by now.
I hear your frustrations and I wish I could give you some advise because I sure have had several issues with my project:Well, I officially give up. I've spent well over $1,000 on everything to hopefully get everything up and running. Had 3-4 other people more knowledgeable than me do a paid house call to help troubleshoot. Can confirm that the Pi Position and Raspberry Pi get power. All of this may just be way over my head.
Anyone that wants to buy this complete setup from me, hit me up. Complete with Pi Position, Raspberry Pi 3+, SD card with image loaded and cable. According to everyone else, this should be 100% plug and play. I just can't get it to work. To say I'm frustrated is an understatement.
Will sell for whatever someone wants to offer me. Or trade for a 6-pack of beer. Don't care at this point.
Wow that is wild! How can so many people be issue free if it was a code issue. Amazing of your friend to give it a try though.Mine switches games even with the button removed, tried new software, new card, new Pi, etc. my latest is a friend is going to attempt to rewrite the code lol
I'm having the same issue with the sync issue, I've tried the newest version of software and the issue is on 3 different monitors. Where can I get a copy of the original pi position software to see if the sync works ok.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.
What does it do when you power it up?Well, I officially give up. I've spent well over $1,000 on everything to hopefully get everything up and running. Had 3-4 other people more knowledgeable than me do a paid house call to help troubleshoot. Can confirm that the Pi Position and Raspberry Pi get power. All of this may just be way over my head.

I thought this was an ArPiCade thread, but oh well I am here now. Disclaimer: I don't own a Piposition.Follow up question, some players when they get to that tight left turn on Fuji like to spin the wheel. On real boards the car would keep turning left as the wheel spun, in Pi Position, once the wheel goes too far it starts turn the other direction. I keeps flipping between left and right as you spin the while in one direction, rather than staying in the direction the wheel is spinning. Is this normal for Mame? Or is there a setting to change that?


thanks for your help. where do i put your new file? i downloaded it and when i look thru my sd card i dont see any file named pp_joy4r2.ino. the closest i found was in the avrup_old folder and it is pp_joy.ino.leonardo.hex and pp.joy.ino.leonardo.hex.orig. also the avrup folder is empty if that means anything.I've fixed the problem that caused inputs to be lost when the steering wheel was turned too fast.
As I mentioned in my previous post, the original code in pp_joy4r2.ino uses polling and, in my opinion, it's not the best solution. In my version (which ChatGPT generated for me, it worked on the first try and I haven't changed a single comma, I just added the comments) interruptions are used.
The new code: https://mega.nz/file/KxwhWKoQ#c3oVcwfc3uJa3yaP9fbjt9mZFgcEVBCZ9TpaHILD_ug (my conversation with ChatGPT: https://chatgpt.com/share/281cd5a1-7298-4755-85a6-4d8c9c9672f0)
It works like a charm and now I can play PP/PP2, Super Sprint, and other games like I'm used to.
Vídeo using the new code:
I just need to adjust the steering wheel sensitivity in mame so that the feel is exactly like the original machine.
This is about updating the Arduino firmware, you can use this post as a reference: https://forums.arcade-museum.com/th...sition-q-a-support-thread.478900/post-4719355thanks for your help. where do i put your new file? i downloaded it and when i look thru my sd card i dont see any file named pp_joy4r2.ino. the closest i found was in the avrup_old folder and it is pp_joy.ino.leonardo.hex and pp.joy.ino.leonardo.hex.orig. also the avrup folder is empty if that means anything.
