Lakka started as an OpenELEC fork with Kodi removed and RetroArch added, simple as that. I've done the same without removing Kodi, use Emulationstation as frontend and have added quite a few other emulators where there isn't a proper libretro core. I've also added quite a few optimizations and other useful features as described on the first page.
I want you to read the first page.
While I appreciate the donation, at this point I don't understand how I can make things any more clear. Once you follow the two points I've written to you then I'll try to help you.
EDIT: The wiki link about the logshare seems to have changed, so I've updated the first post accordingly.
So basically, you still haven't read the first post. Especially the part in red with huge letters.
1. I don't need your Kodi log, or whatever log you think I need. I need the one I specifically ask for and have linked to in the first post.
2. You should check against regular LE, as I specifically have asked for.
Don't really understand why this is so difficult to people. Just makes me less and less inclined to provide any support when people don't even bother to follow directions.
I think you should read the first post.
Let me see, spend countless hours on hardware I don't have or even like... Uhm no 
exFAT should be as fast as other fs on macos.
I thought it was obvious it was a pulldown with an arrow on the right and all Probably wouldn't hurt if nothing was selected and the text was "Click to see available downloads". RPi is the default which is why it shows the logo and text according to that choice.
1. This is LibreELEC, not OpenELEC.
2. The "Generic AMD/Intel/nVidia" release is on the front page downloads, how are you missing it?
You're in the wrong place, LibreELEC is just a distribution. The filesystem code is in the kernel, the LE devs do not write kernel code.
As for HFS+, it's only properly supported with journaling turned off. If you need cross platform R/W go with exFAT or UDF.

Sure it can be done, you have the source 
1. Emulationstation is just a GUI to run ROMs with the correct emulator. It has nothing to do with controller support in games. Moonlight is an nvidia game stream service, has nothing to do with ES either.
2. Works same as other LibreELEC updates.
3. Once for every application that doesn't auto detect it.
4. You'll need to be more specific. I don't have any audio issues, do you?
5. RetroPie is based on Raspbian, this is based on LibreELEC. Once you learn about LibreELEC, you'll understand the advantages. If you have Intel hardware, DRM/KMS mode in RetroArch is much better performing regarding input lag. The integrated RetroPlayer in Kodi won't be as good until Kodi runs on Wayland. Personally, I don't see RetroPlayer going anywhere. This build stops Kodi completely when running emulators to free up memory and increase performance.
I've uploaded new builds, kernel updated to 4.14.
You can use volumes (-v) to create persistent storage that survives reboots.

No, sorry. This is not normal though, does it happen on a clean install?
I ship snes9x2010 for RPi, not snes9x. So no, I can't fix it as I didn't build whatever core you are using.
