@helloThere poor performance in mupen64plus-next is expected right now, i just wouldn't expect it to crash, so now that's fixed i'm happy :) i would use standalone mupen64plus-gliden64 until we have news on -next.
Hey thanks for your help, I actually have solved the problem via first installing raspbian then retropie following the video below after installing with NOObs and now I everything works as intended.
Still have no idea why the boot didn't work for me but at this point I am more interested in relaxing and playing some lovely 8bit games on my Picade. May be I can bump this later on when my curiosity kicks back in.
Thanks for the hints !
I just tested seafile. It doesn't seem to have recurrent tasks that load the system like owncloud.
But nearly everytime I go on a page of the UI, python takes 100% of 1 to 2 cores during 5-10s, which is the time the page takes to load on my local network (withe empty repository - sic).
Moreover, unlike owncloud, seafile doesn't allow to mount and use various external storages (including SMB, S3, google, ...).
It's an interesting software, pretty easy to configure, but the more I test, the more I think the RPi kind of lacks power for this kind of applications, especially if it already hosts retropie.
Whoever could solve the problem with sound on SNES emulator PI3B, PI3B+
The solutions described "https://retropie.org.uk/docs/Sound-Issues/" do not work.
Very disappointed in Raspberry.
Sound sometimes slows down and collapses.
a few days later .... after reading a lot of unnecessary information
The problem was in throttling.
avoid_warnings=2 means don't show the warning squares and don't disable turbo mode on under-voltage condition. We still throttle on over-temperature.
