Emulationstation issue - idle game selection change

mitu

Sorry, I have no further ideas besides what I've already written before.

My idea of disconnecting was to completely disconnect the devices and use a keybooard or an USB controller only just to see if any ghosting still shows up.

Thanks. I can do full disconnection but need to do couple of modification on the wires. Nothing complicated but at this point what this test could tell us?

Many thanks again.

Whether the 'ghost' inputs are caused by your inputs or there's a bug in EmulationStation caused by your config/rom list.

Completely disconnected both controllers and used Keyboard, but issue persists. We can def agree that this is a bug somewhere then.

ES Log

Is there any setting in emulationstation I should consider doing? All video snaps/screens have been fetched via Skraper, is there any particular setting I should be using there as well (I'm not super familiar of the skraper but was quite intuitive on how to be used)?

Many thanks

From the log, I see the joysticks are still detected and there's still input being processed from them. Are these (JammaPi) using a special driver ? How did you configure them in Linux ?

Probably they’re still detected because the microcontroller sits within the GPIO->Jamma board and of course I’m not able to disconnect that.

I’m not sure about the configuration, this is the script used for the installation where I’m sure the answers are. Apologies but my linux knowledge is quite basic. If you visit the link you’ll be able to see the code which seems not complicated.

Try removing the kernel module joypi with

sudo rmmod joypi

maybe this stops any processing done for the inputs.

@mitu

that command solved the issue. No more ghost inputs. But of course no joystick input.

Is there anything I could do more to fix the root cause?

Many thanks

At this point I think the bug is in the joypi module - you should report this to the author of the module and ask them for further support. Maybe there's some additional configuration that would fix this behavior or even a patch to stop the ghost inputs.

@mitu
Thanks. The project seems abandoned but I’ll try to seek for some support.

I just realized I have a coin counter connected to my two coin purses which has a diode on the 12v which seems to be shorted. You might recall that some users reported long time ago ghost inputs due to issues connected to 12v. You think the diode is a path worth to be explored? Many thanks!

@ilpappa unfortunately I'm not the one to give advice about electronics - I don't have enough knowledge/experience.
