Hello,

 

I installed Retroarch from the repos, tried to install a "core" from the Retroarch updater but no cores were available. I searched about that if the installed version is too old no cores will be available, so I added the Retroarch ppa and installed the newest version, but got the same problem.

 

Does Retroarch work under Armbian? Do I need to manually install "core" binaries? If so, where can I get them?

 

Thanks.

What image are you using? There are many ways to install this. I'd advice to start with a fresh, current jammy and build retroarch yourself.

The problem is that RetroArch doesn't provide arm64 cores.

 

There are gaming images for arm64 boards that include these cores. Good luck.

I'm using the latest Ubuntu-based Armbian stable for Nanopi M4v2.

 

Thanks for the answer, I'll try to build the cores from source.

 

From what I understand, the current kernel does have 3D HW acceleration for Mali-T860, right?

Yes. Panfrost GPU driver is enabled on all images for M4V2/RK3399.
