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.
