I installed Ubuntu 21.04 on my Raspberry 4 B, and installed Retroarch 1.9.1 on top of it.
Once I launch a core I got the error in the logs: [ERROR] Error(s): /home/framby/snap/retroarch/455/.config/retroarch/cores/snes9x_libretro.so: wrong ELF class: ELFCLASS32
I assumed I should use this url for downloading the cores: core_updater_buildbot_cores_url = “http://buildbot.libretro.com/nightly/linux/armv7-neon-hf/latest/”
I tried to troubleshoot and test with http://buildbot.libretro.com/nightly/linux/armhf/latest/ , or http://buildbot.libretro.com/nightly/linux/x86_64/latest/ , but in vain.
I looked at Dosbox core does not load (Retroarch 1.8.4 PPA on Ubuntu19.10) , but no solution here
I understand something is missing to load the core and possibly I’m not using the right core updater url, but honestly, after two days to read lot of forums, I’m puzzled.
Is there an honorable soul to help me ?
