- Enhanced `runemu.sh` to conditionally enable debug logging based on system log level, improving performance and debugging capabilities.
- Introduced functions to pause and resume background services during gameplay to optimize resource usage.
- Updated `retroarch.cfg` to disable frame delay and set video context driver to default, improving compatibility.
- Changed DuckStation's GPU renderer from OpenGL to Software for better performance on RK3326.
- Adjusted Flycast settings to lower resolution and optimize rendering settings for smoother gameplay.
- Modified MelonDS script to correctly handle internal resolution and screen orientation settings.
- Updated PPSSPP configuration to improve frame skipping behavior and adjusted CPU speed settings for better performance.
- Refined GPU driver scripts to handle panfrost availability and ensure proper driver binding, preventing graphical issues.
- Removed obsolete panfrost quirk file and migrated relevant settings to a new profile.d script for better management.
- Added service condition checks for various network daemons to ensure they only start if their configuration files exist.
- Adjusted systemd service configurations for network daemons to improve reliability and resource management.
- Updated sysctl settings to optimize memory management and reduce unnecessary RAM usage.
- Disabled debug shell service by default to enhance security and resource efficiency.
- Created necessary directories for mesa shader cache to ensure persistent shader caching across reboots.
- Added a new squashfs package for weston to support graphical environments.
Flasher verification:
- Move read-back SHA256 verification BEFORE boot partition modifications
(DTBO copy, variant write, extlinux switch). Previously verified AFTER
modifications, causing guaranteed hash mismatch (false positive).
- Remove duplicate verification block at end of script.
Kernel:
- Restore DRM_FBDEV_EMULATION=y (disabling it broke display on some setups
that depend on /dev/fb0 for initialization)
Panel overlays:
- Restore early return for odroidgo3-compatible devices in archr-dtbo.py.
R36S base DTS already has reset-gpios/power-supply/backlight - adding
them again in the overlay caused conflicts. Overlay only needs
panel-init-sequence and display timings.
- Regenerate all 32 DTBOs with correct behavior.

All 32 panel overlays regenerated after removing the premature return
in archr-dtbo.py. Panel 4 DTBO now correctly includes reset-gpios,
power-supply, and other hardware properties that were previously missing.
Panel 4 DTBO size: ~800 bytes → 4045 bytes (now includes full hardware config)

Critical fixes:
- archr-dtbo.py: Remove premature return for odroidgo3-compatible devices
that was skipping hardware property generation (reset-gpios, power-supply,
backlight-supply, enable-delay-ms). This is the ROOT CAUSE of Panel 4
wrong image and vibration issues reported by users.
- RetroArch: Switch from glcore to gl (more efficient on Panfrost/Mali-G31),
increase swapchain images from 2 to 3 (better frame pacing on Mali)
- DraStic: Disable hires_3d on ALL RK3326 configs (Mali-G31 lacks power for
high-res 3D rendering, was causing frame drops in NDS games)
- EmulationStation: Bump to latest with performance optimizations

- Modify joypad compatibility to include "archr-joypad" in the device tree source.
- Adjust internal display settings to use the same reset GPIO and add enable GPIO.
- Remove SDIO card detect GPIO and mark it as non-removable.
- Update the joypad driver in the MIPI generator to use "archr-joypad".
- Fix Vulkan custom dispatchers to restrict header version checks.
- Add system manager timeout overrides for improved shutdown performance.
- Update kernel configuration to version 6.12.79 and enable BFQ I/O scheduler.
- Clean up GPU governor settings in post-update scripts.
- Update PPSSPP emulator to version 1.20.2 and apply necessary patches.
- Adjust SDL2 and Mesa package dependencies and versions.
- Update Vulkan headers and loader to version 1.4.347.
- Add udev rules for BFQ scheduler and systemd configuration for shutdown timeout.
- Implement input sense adjustments for better button mapping.
- Add clock speed settings to EmulationStation configuration.
- Disable rumble motor on boot to prevent unwanted vibrations.
- Created boot.ini files for Panels 0 to 6 with boot arguments and loading instructions.
- Added device tree binaries: rk3326-r35s-linux.dtb, rg351mp-kernel.dtb, and rk3326-rg351mp-linux.dtb for each panel.
- Introduced a new boot.ini for R46H and RGB20S with specific boot arguments.
- Updated generator.sh to prevent script abortion on individual panel failures.
