- input-merge daemon: combines gpio-keys + adc-joystick into single
virtual "Arch R Gamepad" via uinput so RetroArch sees one device
(fixes analog sticks ignored due to max_users=1)
- retroarch-launch.sh: start/stop input-merge, VT blank on launch
- retroarch.cfg: ROCKNIX-based tuning (48kHz audio, triple buffer,
late input polling, autosave, core options path)
- retroarch-core-options.cfg: per-core tuning from ROCKNIX RK3326
(mupen64plus, pcsx_rearmed, flycast, mame2003-plus, melonds, etc.)
- archr-gamepad.cfg: autoconfig for merged virtual device
- panel-detect.py: panels in numerical order (beep count = position),
default_panel searches by empty dtb_name instead of panels[0]
- build-rootfs.sh: compile input-merge, install core options and
autoconfig, add input-merge and kill to sudoers
