Batocera 43 Brings New Life to Android-Based Handhelds
The latest Batocera 43 update is a significant leap for handheld emulator fans, especially those on Android-centric devices. Initial support has arrived for the AYN Odin 2 Mini and AYN Thor, alongside the Retroid Pocket 6 and PowKiddy X55, while a wide range of Anbernic RG-series devices also join the roster. For SM8250 and SM8550 systems, Batocera now uses a unified image with device selection in the bootloader, though users must upgrade the Android Bootloader before migrating. Beyond broader hardware coverage, Batocera 43 refines the software stack: Cemu support lands on SM8550 devices, EmulationStation gains LED colour control and multi-screen brightness options, and a virtual keyboard appears for Wayland touchscreens. With DraStic removed and Azahar reworked, the focus clearly shifts toward open, maintainable components that can scale across emerging handhelds.
KNULLI Scarab: A Major Firmware Refresh with RetroArch 1.22.2
KNULLI Scarab marks one of the most ambitious handheld firmware updates in the project’s history, doubling down on both compatibility and quality-of-life improvements. The release expands support to more than 15 handhelds, spanning devices like the TrimUI Smart Pro S, Anbernic RG Vita Pro, RG DS, and several Retroid models including the Retroid Pocket 5 and Pocket Flip 2. At the core of the update sits RetroArch 1.22.2, complemented by a new standalone Yabasanshiro build to significantly boost SEGA Saturn performance. Syncthing integration has been overhauled, allowing manual or automatic syncs triggered on game exit, with notifications tracking transfer progress. BatteryPlus introduces more precise battery readouts, while the Silky RGB system refines RGB lighting control. Because Scarab restructures files and alters partition tables, users are encouraged to re-flash and back up, underscoring the scale of this firmware overhaul.
Anbernic RG DS Finally Gets a Dual-Screen-Friendly Linux Firmware
Anbernic’s RG DS is receiving a long-awaited Linux firmware that finally embraces its dual-screen design instead of leaning on the original Android setup. The new system aims for a more authentic Nintendo DS-style experience, with a cleaner interface than the stock Android launcher. Anbernic ships three exclusive themes—DS Dark, DS Light, and Classic Style—catering to users who prefer either a modernized look or a faithful take on the original UI visuals. Practical enhancements include independent brightness control for each display, an easy screen swapping function, custom font colours, and a revamped graphical button test interface. Crucially, this Linux build runs from a microSD card rather than internal storage, making it easy to test without committing to a full flash. Powering off, removing the card, and rebooting returns users to Android, offering a reversible path for experimentation with dual-screen-optimized firmware.
A Converging Firmware Ecosystem for Retro Handhelds
Viewed together, Batocera 43, KNULLI Scarab, and Anbernic’s new RG DS Linux system illustrate a rapidly converging firmware ecosystem for retro handheld gaming. Developers are prioritizing multi-device compatibility, as seen with Batocera’s unified images for SM8250/SM8550 devices and KNULLI’s growing list of supported handhelds, including Retroid and Anbernic families. Performance and usability tweaks—such as RetroArch 1.22.2 integration, Yabasanshiro for Saturn, multi-screen brightness controls, and refined RGB management—underscore a shift from basic “it runs” support to carefully tuned experiences. Meanwhile, features like improved Syncthing sync workflows and microSD-based OS testing on the RG DS signal a desire to reduce friction for users experimenting with firmware. As more devices like the Retroid Pocket 6 and AYN Odin 2 Mini join this shared software landscape, handheld emulator updates increasingly feel like platform-wide upgrades rather than isolated device patches.
