System daemons: hotkeys (volume/brightness), automount, bluetooth agent, memory manager, sleep/suspend, USB gadget mode, save-config persistence. Boot splash: initramfs SVG renderer (fbsplash + svg_parser) for 0.7s splash. Panel tools: generate-panel-dtbos.sh rewrite, convert-panel.py for ROCKNIX panel data extraction, archr-dtbo.py for runtime overlay management. Input: archr-gptokeyb.c gamepad-to-keyboard mapper via uinput. Launch wrappers: emulationstation.sh and retroarch-launch.sh updated for KMS/DRM + Mesa 26 Panfrost environment.

# Arch R - RetroArch Launch Wrapper
|
|
#==============================================================================
|
|
# Launched by ES via es_systems.cfg. Ensures ALSA mixer state, sets
|
|
# performance governor, and launches RetroArch with proper environment.
|
|
# After RetroArch exits, restores ALSA mixer state (like dArkOS verifyaudio.sh).
|
|
#
|
|
# Usage: retroarch-launch /usr/lib/libretro/<core>.so /roms/<sys>/rom.ext
|
|
#==============================================================================
|
|
|
|
# Root guard: RetroArch must run as archr, never as root
