@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)
@juliano-gonçalves-lima I tried the core redream_libretro through the Lakka distrib and it's super slow on a pi 3 even cranking the overclock to 1400 Mhz. When i get around 45-50 fps on soul calibur using reicast, i got only 15-20 using redream_libretro
This core is too "heavy" on CPU resouces for any Pi at the moment so there is really no point in integrating it in Recalbox so far.
Armhf cores do not always work on recalbox 
Former dev - Please reply with @substring so that i am notified when you answer me
Ex dev - Merci de me répondre en utilisant @substring pour que je sois notifé
@substring Yes of course :=) ! But some of them work really well like for example the Quake emulator libretro_tyrquake which is not still officially integrated in recalbox (at least i think it's not but maybe i'm wrong)
@gkralicek2 it's not, and no reason to add it anyway. If we add 1 system per sibgle game core, themers will hate us

@substring i see :=)
@gkralicek2 hank you, for testing let's wait for a raspberry pi 4 who knows we can run more games!

Anyway we will add it on x86_64 version in the next months, but not in arm boards that are not powerfully enough to use it.
No surprise. If I said that in my first post that is because I already tested this emulator and I know that it didn't include a dynarec.

Thats good to know, is it possibel to also update the actual RetroArch progmram to 1.7.1?.
Hopefully the devs can add it to the UI in the next update to have a 'Update RetroArch' and also a 'Download Retroarch Cores' options

It clearly not will be added, it is not in the philosophy of Recalbox, which is to the most plug and play, safe and easy to use.
Thus adding a core on Recalbox is not just downloading, it requires writing configuration to handle all kind of controllers and screens to be handled automatically, plug n play, without any configuration to be done by the user.
If you want something configurable as much as you want, Retropie already does that.

Yet Recalbox allows you to select an emulator to use!!
If the core is already usable in Recalbox then how would adding a 'update core option' be unreasonable as everything would be setup for that core already?
Or failing that have an 'advanced user' mode in the options were enabling this would allow such features?

Because if a core ie updated, it might not work with configuration from before.
And because it will add another level of support to do for code which would be outside of what is integrated into recalbox, so support nightmare
I wouldn't trust the armhf libretro buildbot it's not very up-to-date, all cores are not built ...
