Anything like this would work well with an IPAC 2. https://www.amazon.com/Coin-Acceptor-Programmable-coin-types/dp/B01EAI1KAQ/ref=sr_1_5?ie=UTF8&qid=1508800034&sr=8-5&keywords=coin+acceptor
For arcade games, just program the coin acceptor as the coin in the arcade machine, (instead of using select or some other key on a keyboard).
I made a homemade coin acceptor with a few wires and some metal sheet, I don't recommend it but it worked just wiring it up to a button.
here is a good video on how to set up a generic coin acceptor with retropie

Thanks for the continued help...you guys are really awesome!

I mamaged to create an Ssh and used winSCP to visually check the directories but I couldn't find default.cfg file at those locations? Managed to find all my recent Rom cfg files and removed those. Ran a search for the whole sd card for default.cfg and found it relating to lr-mame2003 but with a different pathway(file had unreadable symbols) Removed that and rebooted.
I feel really successful in what I have learned the last few days but my S,Q,W keys are still bound!? I'm using a conventional usb keyboard tonight at home so the issue doesn't seem to be related to my iPac.

My next plan is to change the key definitions in winipac for the iPac board. My player 1&2 pin numbers sw7 & 8's are not used so I will try swapping these keys designations over.
S-L
Q-K
W-C
This will hopefully change the conflicting s q w keys to unassigned pins. L K C don't seem to have any adverse effects in mame. So this might be the solution. On the plus side I've learned heaps the last few days-never thought I'd be able to this stuff

Can I remove my keyboard as a controller? i dont actually want to use to play games. would that help?

You should provide a full log also as it will contain other info (such as the full commandline). And make sure you have the correct bios files installed.

@pjft Hi thanks, yeah DD was one of them and a couple of other Arcade. No worries, maybe its a common thing with particular titles then - Thanks

@mitu oh, thanks! Had missed that post.

@markwkidd

Thank you, I've open the issue "Outrunners single screen mode" in lr-mame2003 Github

@darksavior Thats looks great.......i'm going to hopefully get it sorted once i'm home....Cheers again...

@meleu I remember having myself a problem when trying to save the core config overrides for PS1 from the retroarch menu - and I've seen similar reports at https://retropie.org.uk/forum/topic/8527/psx-remaps-failing or https://retropie.org.uk/forum/topic/8527/psx-remaps-failing - that's why I thing that it might be a permission problem with saving the core specific options for the PS1 core.

That video worked fine for me with an original SNES controller. What problem are you having?

@sirhenrythe5th No, not at all! "Navigation Sounds" does indeed suggest what you understood.

I'm not fully sure why that would be related, but in that case maybe that option could be renamed. :)

Thanks!

@red2blue said in Arcade Questions (Romsets, Updating, MAME FBA):

@dankcushions so i finally got the 0.2.97.42 romset, when i replace my 0.2.97.39 romset do i overwrite the .39 roms or can i just skip???

some .39 ones will work in current FBA, some won't. i personally replace all.

also when i compare, 2.97.39 is 10 gb's larger than 42's

sets can be merged, non-merged, complete, just parents, etc. all these methods result in different sizes. there's various ways of building a romset, and i guess your two sets were done in different ways.

Eh, what exactly do you mean by 'getting stuck in Kidmode'?
Do you mean you cannot unlock the UI mode back to full? Or that you want to revert to stock ES?

yes, I've posted to DFRobot Bluno Bee forum. Hopefully, there'll be a reply soon.

There's a suspicion on the Raspberry PI forum that BLE devices are not supported in Raspbian. Interesting ...

Anyway, if anyone has a BLE device or gamepad working in RetroPI, that'll help a lot!
