OpenEmux 1.10.2

OpenEmux 1.10.2

A single fix, for the mirror image of the last one: this time it was the Flatpak that could not play games.

Flatpak: no game would launch

If you installed both OpenEmux and RetroArch as Flatpaks — the setup our own install instructions recommend, and the natural one on an immutable distro like Fedora Silverblue — clicking any game failed with "No RetroArch core found", no matter the console, and no matter how many cores you had installed through RetroArch. Reported by Marc Mader in #179.

The cores were there all along. OpenEmux looks for them exactly where the RetroArch Flatpak keeps them, ~/.var/app/org.libretro.RetroArch/config/retroarch/cores — and our manifest asked for access to your home directory, assuming that covered it. It does not: Flatpak hides ~/.var/app from other applications' sandboxes even when they have access to everything else in home, precisely so one app cannot read another's private data. So OpenEmux looked in the right place and saw an empty world.

The fix

The manifest now declares a read-only grant for the RetroArch Flatpak's directory. OpenEmux can see the cores again — and only read them; it still cannot write into RetroArch's data. Installs that pair OpenEmux with a native (non-Flatpak) RetroArch were never affected.

If you don't want to wait for the update, the same grant works from the outside on any existing install:

flatpak override --user --filesystem=~/.var/app/org.libretro.RetroArch:ro io.github.guilhermefeitosa66.OpenEmux

After updating to 1.10.2 that override is no longer needed and can be dropped:

flatpak override --user --reset io.github.guilhermefeitosa66.OpenEmux

Verify what you downloaded

Every release ships a SHA256SUMS file. Download it next to your artifact and run:

sha256sum -c SHA256SUMS --ignore-missing

OK means the file is exactly what was published. Anything else means it is corrupt or has been tampered with — don't run it.

Upgrading

flatpak update brings the new permission with it — nothing to configure, and Flatpak will list the new filesystem access for you to see. Settings, playlists, artwork, save states and input profiles are all kept. The .deb, .rpm and AppImage are rebuilt for completeness but carry no behavioural change.
