Drop the pointless zip wrapper around the x86_64 AppImage, harden HostShell
so bundled curl keeps APPDIR libs while host curl scrubs LD_LIBRARY_PATH /
Steam LD_PRELOAD, and add a Flatpak channel with --device=all, bundled
curl, and AppStream releases metadata. Portable mode now probes writability
with a unique temp file and falls back soft on RO mounts / Flatpak.
Ships a dual-NRO native launcher that checks GitHub Releases, updates both NROs from gen1recomp-*-switch.zip with matching NACP versions, and stays silent unless an update needs confirm.
