Finally the solution was to change the permissions of this folder /usr/lib/x86_64-linux-gnu/libretro/ (see precedent post).
But I have a ~/.config/retroarch/cores folder, and this one is empty.
I would like to set this folder as the default one for the cores (and not the /usr/lib/x86_64-linux-gnu/libretro/ ). At first, is this a good idea ?
If it’s a good one, I would like to know how to do this.
When I launch retroarch, he 's reading the ~/.config/retroarch/retroarch.cfg :
$ grep retroarch.cfg retroarch.log
stat("/home/yann/.config/retroarch/retroarch.cfg", {st_mode=S_IFREG|0644, st_size=101860, …}) = 0
openat(AT_FDCWD, “/home/yann/.config/retroarch/retroarch.cfg”, O_RDONLY) = 3
stat("/home/yann/.config/retroarch/retroarch.cfg", {st_mode=S_IFREG|0644, st_size=101860, …}) = 0
openat(AT_FDCWD, “/home/yann/.config/retroarch/retroarch.cfg”, O_RDONLY) = 11
openat(AT_FDCWD, “/home/yann/.config/retroarch/retroarch.cfg”, O_WRONLY|O_CREAT|O_TRUNC, 0666) = 11
Remarque: retroarch.log was created by strace -o retroarch.log retroarch
But when I look at ~/.config/retroarch/retroarch.cfg, I don’t see where to set that.
Do you have any idea ?
Thanks.
