@voljega When opening retroarch and selecting update core, it displays the content of https://buildbot.libretro.com/nightly/linux/armhf/latest/
A core can then be selected and downloaded but it's stored within retroarch folders and needs to be moved manually to the proper recalbox core folder afterwards.
I did it to update my mame2003 core with the latest version from 30/03 which eventually solved the annoying sound problem in mortal kombat 1 (the voice constantly shouting "finish him" in the character selection screen instead of pronouncing the character's name)
