Almost finished home RasPi 3B, Issue with Controllers, Need fresh minds

@mitu Thanks for the reply, I hear you on time.

This paste is an attempt to load Sega Genesis after plugging in several controllers. In MC, many of these lines are in red, but I wasn't able to copy it over like that. Not sure if it matters, but they were almost all in the Retropad section.

/opt/retropie/configs/all/retroarch.cfg is the correct file that I changed. But I don't know if 16 is what it's telling me is the max or if it's just a default setting.

I have both powered and unpowered USB hubs here, and both 3.0 and 2.0. All have the same issue. What I tried earlier is splitting the controllers between 3 powered hubs (plugged into different ports on the pi), and got the same result.

Here is the result of dmesg..

The article was an interesting read and now I'm curious about how much the 'full-speed' of the device matters. But I haven't sifted through this one yet...

And I just looked up the error at the end of the crash info..

https://retropie.org.uk/forum/topic/11221/runcommand-segmentation-fault-after-update-today/11

I did consider going through and listing everything that was 'unset' to 'disabled'....think that might be it?

You've used the 'Save/Reset Configuration' from RetroArch - despite my advice not to so - and your BIOS dir doesn't exist anymore

[WARN] SYSTEM DIR is empty, assume CONTENT DIR /home/pi/RetroPie/roms/megadrive/Sonic The Hedgehog (USA, Europe).md
[INFO] Environ SYSTEM_DIRECTORY: "/home/pi/RetroPie/roms/megadrive/".

I don't know if that old topic's info applies to your error, from the log file you're either missing the BIOS (which is understandable, since your BIOS folder is unset) or the ROM is not correct.

Your dmesg output shows USB bus disconnects, so the configuration is clearly not working because of USB connection getting reset.

I'm not entirely sure what you're referring to.. I didn't use RetroArch to do anything recently. In fact, I just reinstalled from source last night. BUT I can't open the GUI still for Retroarch. That crashes also, from the RetroPie Setup screen.

As for the BIOS or the ROM, they all work. If I only plug in a couple of controllers, every single ROM and emulator works.

I'll take a closer look at dmesg, but what I was doing right now is reading about segmentation faults, which appears to be pretty widely varied.

I am going to try to turn off auto-config and/or RetroResolution's fix here, real quick.

On a default install the SYSTEM_DIR is set to /home/pi/RetroPie/BIOS, your log shows otherwise.

EDIT: if you manually modified the retroarch.cfg, you shouldn't remove the already existing settings.

Segmentation fault means RetroArch crashed. It's usually a ROM or BIOS issue, but your case it might be related to the joypad connections.

The BIOS directory is there, with a last modified of May 9th.
Something I need to move or change there?

I think you misunderstood what I said - you've modified the retroarch.cfg (either editing or using Reset) and RetroArch doesn't know about this folder to search for BIOS files. Look at my previous reply - where I've outlined the lines from the log showing that.

tjayhawk32

@mitu Apologies, I follow.

The reason I said a few lines back that I didn't know 'which' retroarch.cfg to go into might have something to do with this.

I have one here
https://imgur.com/81FbkC3
which is at /opt/retropie/configs/all/retroarch.cfg

And this much more complete one
https://imgur.com/DWuZAeA
Which is at /opt/retropie/configs/all/retroarch/retroarch.cfg

Is this unimportant or does the second one need to be a directory back?

EDIT: Also, I'm going to double check this but I am 95% sure this issue of too many controllers = emulator no longer loads is exclusive to the libretro emus, so far with the exception of DGEN which just went to a red screen and paused there.

That file is not used by RetroArch on a normal RetroPie installation, only the former.

tjayhawk32

@mitu Ah, so it's at least supposed to be there.

Does the first one look wrong or that it's missing something? Not totally sure what to to next.

tjayhawk32

Here's what I think I'm gonna do today later...
I ordered an external hard drive that I'm going to use for ROMs instead of the SD card I have in there to be able to get more stuff on there.

I was going to try to clone it, but if I just do a complete fresh install, would that fix this controller issue in your reasoning?

And do I need to clear the SD card first? (I have all the ROMs on another external drive...scraping again will suck though.)

And @mitu , I see how many times youre reaching out on here to guys in need of help. You're an all-star, thank you.

Unlikely, this seems like a hardware limitation - but don't take my word for it, since I'm not an USB expert. Out of curiosity, did you try this combination on a PC ? Do all USB controllers get detected and working all at once ?

DetroitKp

@mitu Hi Mitu. Why does 'Save Configuration' in RetroArch or 'Save Configuration on Exit' mess up the controller config? I think that was one way to make controller modifications.

mitu

@DetroitKp Because RetroArch is started for each system with a different config file - see here. When you're saving a config, you're saving the system's config file and if you're starting on another system, you get a different config (not the one you saved).
If you need to make modifications to the controller config, use the Core input remapping - explained on the same page. This saves the configuration as a remap (.rmp) file which touches only the input, without interfering with the global settings, plus you get the ability to map it per game or per core. If you use 'Save configuration', you get the same settings for all games from the same system, which might not be what you want.
There are also another side effects, but I can't find the that old topic (a few years old) that discusses this.

Is there an easy way to do this without installing Ubuntu and RetroPie on my PC?

Yes, you can use your Windows installation and install RetroArch to see how it works - it has also a Windows version. You'll have RetroArch standalone, so no Emulationstation or joystick/gamepad configuration dialog - you'll have to do that from RetroArch.

mitu

Or you could download Lakka, which is a live Linux distro with just RetroArch, just like RetroPie, but based on a different Linux distribution model.

tjayhawk32

@mitu Starting now.

Also idk if this matters, but all of the controllers are active in the menu.

I can't get it to log anything, so hopefully this helps. There are a total of 8 ports being used on the hub for this, with a few of those having dual ports like N64, Genesis and DC.

Curious if the ones that showed up as 'not configured' were the reason those emulators stopped launching, I tried selecting the ones that did configure back on the RetroPie, and even unset, with the same crash result on Genesis.
