These should not be provided by the gnome-games package, they're already in https://archlinux.org/packages/community/any/libretro-core-info/
Comment by Balló György (City-busz) - Monday, 19 April 2021, 09:23 GMT
It seems that *_libretro.info files and *.libretro files contain different set of information:
https://github.com/libretro/libretro-core-info/blob/master/dolphin_libretro.info
https://gitlab.gnome.org/GNOME/gnome-games/-/blob/master/flatpak/libretro-cores/dolphin.libretro

I'm not sure what would be the best way to provide these *.libretro files. I can add those files available in the gnome-games repository[1], but it's probably incomplete, since we have different set of libretro implementations in our repositories. Or we can add *.libretro files to the individual libretro packages like Debian and Fedora do, but it means we have to maintain them downstream.

@Alucryd: What is your opinion?

Oh, you're right those are different indeed. Since they're only required by gnome-games I'd rather have gnome-games ship them. I can certainly add missing libretro cores upon request, but missing *.libretro files should be dealt with upstream imho.

I added the *.libretro files in gnome-games 40.0-2. I also added those libretro-* packages to optdepends, which already present in the official repositories.

@Alucryd: according to the upstream documentation[1], I can add support for more platforms if you are interested in packaging them:

We already have mednafen_pce_fast: https://archlinux.org/packages/community/x86_64/libretro-beetle-pce-fast/

As for the rest, sure, I'll go over them. pcsx_rearmed isn't really useful since beetle-psx is superior in every way, beetle-saturn and bsnes-mercury also have superior alternatives, but options are good I guess. The others I've been meaning to add, so now is as good a time as any. I'll keep you posted.
Comment by Balló György (City-busz) - Tuesday, 20 April 2021, 12:39 GMT
I made some changes on the list:
- Removed mednafen_pce_fast as it's already in the official repositories.
- Removed mame and mednafen_saturn, because they are reported as broken by upstream.
- Added gearsystem and handy as these are supported by upstream.

I replaced pcsx_rearmed with mednafen_psx in trunk. Replacing compatible libretro cores can be done easily, so Alucryd, feel free to recommend better alternatives[1] if you know.
