xf86-video-nvidia: update to 381.22I read this wrong, though you meant LibreELEC server side. It already supports SMB2/3, although a client might choose SMB1.
As far as I know, the SMB support in Kodi only supports SMB1. You can however mount using the kernel (i.e. the mount command or create a systemd unit), specifying the "vers=3.0" option.
No it doesn't. There's a PR that will correct it, but it hasn't been merged yet.
Then you should report it in the bug section including full logs and hardware info. The Kodi version does not matter as it has nothing to do with display drivers.
That would be regular LE.
Possibly, as I don't know what's causing your nvidia issue either. Doesn't seem to affect others. Did you try vanilla LE?
Compare with vanilla LE. If it works there, report it in the bug thread. Otherwise, provide full logs from the log share and also tell what GPU you have.
New builds are uploading. Enjoy 
Ok, I see the problem now. New build coming soon 
Again, I have 20170516 on my NUC and clicking Emulators launches ES as it should. So make sure you're on the right version and provide logs.
I don't know what to tell you, it works here launching from main menu.
I'm running 20170516 on my NUC and Emulationstation runs fine.
20170516 fixed build uploaded 
Sounds like you messed up your config, delete /storage/.config/retroarch/retroarch.cfg and try again. And I'm not sure what you mean about bluetooth I never heard about pressing any button to pair, mine works fine through LibreELEC menu, or through bluetoothctl CLI utility.
Sounds odd, the 360 controller should be auto detected in retroarch AFAIK. I can recommend a DS4 which I have configured and tested.
I don't archive older builds as I use my gdrive which is space limited.
Feel free to write a decoder, I'm pretty sure nobody else is working on it.
Sounds like you've overwritten your /flash/config.txt and removed dtparam=audio=on which is needed for sound on the rpi. Fix it or do a clean install.
Most likely same issue as highkick05
Yes, everything in this build is supposed to work. Looks like Emulationstation broke in the last build, I can reproduce here as well. Will investigate and fix. My build machine is off and I'm at work, so probably won't be until tomorrow.
RetroArch is a frontend for libretro cores, which is basically standalone emulators. You can launch every emulator in this build individually, that's what Emulationstation does.
