[Solved]SNES emulator crashes after a while with bluetooth controller

krozty2112

Hello everyone!

I'm new on retropie and at the first it works great with the most emulators I like to use (NES, MAME, Gameboy Advance, Genesis, etc.), but when I use Snes emulator, and after a while, emulator crashes with no error message, it exit just like when someone regulaty exits from the emulator. And if a save state and the emulator crashes and then load that save state, emulator crashes at the same part where the emulator crash before.

I hope you can help me with this. Thanks everyone and excuse me if I make some grammar mistake writing this post, english it's not my first lenguage.

@krozty2112 hi,
Is your Pi 3 overclocked at all?

krozty2112

@RetroResolution no, it is not overcloked

RetroResolution

@krozty2112 okay. Is the SNES emulator the only one which crashes the Pi? Is your power supply rated at 2.5amps and 5volts?

krozty2112

@RetroResolution only with snes emulators and power supply is rated at 2.5amps and 5v

@krozty2112 unfortunately not much else is springing to mind immediately, as the SNES isn't an emulator I make much use of having never owned the original machine
In case it assists another forum member to help you:

which SNES emulator are you using?
is anything reported in /tmp/runccomand.log after the emulator crashes?
what memory split do you have set up?

My hunch is the bluetooth controller / stack could be the cause, but I don't use bluetooth myself so can't test this. Do you have a wired usb controller you could use instead (or just use your usb keyboard for test purposes)?

@RetroResolution "What memory split do you have set up?"
I don't know, how can I know that?. I'm using the whole sdcard space

"which SNES emulator are you using?"
I try with lr-armsnes, lr-catsfc, lr-pocketsnes and lr-snes9x-next.

I think it looks like is a controller/retroarch issue. I was trying to play using keyboard and occurs the same error so, remap my keyboard and it works fine. I do the same thing with the controller and works fine too, but after a while and from nowhere, retroarch menu appears.

Is it at all possible that your controller mapping is conflicting with the hotkey assigned to quit RetroArch?

RetroResolution

@krozty2112 'memory split' refers to Ram, rather than SD card space, however it doesn't sdound like it's the problem.
As you're getting the issue with several SNES emulators, it's likely either a specific game ROM, or the bluetooth controller.
I reckon it's the controller, but as I don't use Bluetooth controllers myself, I'm afraid I can't help. I'd recommend searching this forum for Bluetooth controller issues in general.
Best of luck.

@mediamogul definitely sounds like this is an issue

After a while and testing the new remap, the issue still happen. Then, I made a test with an USB gamepad (wired) and, after 3 hours, works fine.
I think it's clear the issue, in my case, is the using bluethooth connection.

Searching on google, I found a couple of posts that I think it's same issue happen to me but with ps3 controllers: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=142481 and https://www.raspberrypi.org/forums/viewtopic.php?f=78&t=145807
I will buy a bluetooth dongle this weekend and test it.

Any suggestions?

I read those two links and it looks like a solid candidate for your problem. Good find. Let us know how it works out.

I bought a bluetooth dongle and after testing and playing the whole weekend, finally, no crashes or weird exits on emulators.

First of all, I had to edit /boot/config.txt with nano and add dtoverlay=pi3-disable-bt at the end of the file, with this disable bluetooth on board, save the file and then turn off Retropie.

Then, I connected the bluetooth dongle, turn on retropie and add the controller to Retropie as wiki says https://github.com/RetroPie/RetroPie-Setup/wiki/Setting-up-a-Bluetooth-controller

Thank everyone!
