how to add new core in recabox?

[OyyoDams]

@juliano-gonçalves-lima Hi,

That's not an easy task. If you want to add a core yourself, you have to make a buildroot package and crosscompil it. All is explained here: https://gitlab.com/recalbox/recalbox/wikis/home

@juliano-gonçalves-lima what enhencement coud it give ?

[rockaddicted]

Source code is no more available (and you have to pay if you want a binary) and libretro core is based in last public sources not updated since the fork...
So constant improvements is maybe not the best expression.
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.

I'm sorry but I have no knowledge with programming, I believe I could never add this core, thank you very much I'm looking forward to this new version x86_64, who knows in the near future you do not create one for the raspberry pi

[Gaetan]

It's the second time today I read about this core. Seems to be promising. Apparently Lakka add it. I may give it a try and give my feedback here

[Juliano Gonçalves Lima]

thank you very much, if you need help testing some games you can talk to me

redream_libretro

Can you not just load a libretro core then once loaded go into the libretro core settings (usually your 'shortcut/function button' and 'Button B') then go to 'updater' then 'core' and download the redream_libretro from there?

[voljega]

@blockaboots no you can't, it's recalbox, not retropie.

[BlockABoots]

@voljega I though you can select what core to run for each emulator in the advanced emulator settings??

So say for example i load a MegaDrive game then go into RetroArch settings and update the Genesis GX Plus core it wont actually run the updated version on restart?

[gkralicek2]

@blockaboots No it won't :=(. It will indeed download the updated version of the compiled *.so file but you will need to place it in the /usr/lib/libretro manually afterwards if you want it to be launched next time

[voljega]

@gkralicek2 didn't even knew that was possible ...

[gkralicek2]

@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)

[gkralicek2]

@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

[gkralicek2]

@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)

[Substring]

@gkralicek2 it's not, and no reason to add it anyway. If we add 1 system per sibgle game core, themers will hate us

[gkralicek2]

@substring i see :=)

[Juliano Gonçalves Lima]

@gkralicek2 hank you, for testing let's wait for a raspberry pi 4 who knows we can run more games!

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
