Two Flagship Firmware Updates Land for Retro Handheld Fans
The retro handheld gaming scene just received a major boost with the release of the Batocera 43 update and the new KNULLI Scarab firmware. Both projects focus on making retro gaming more accessible, powerful, and consistent across an ever-growing list of devices. Batocera 43 targets users who enjoy custom firmware on Android-based handhelds and ARM systems, while KNULLI Scarab refines what was already considered one of the best handheld firmware experiences. Each release brings expanded device compatibility, smarter system tools, and notable performance and stability improvements. For players, the practical impact is straightforward: more handhelds can now run more systems, with better controls, cleaner interfaces, and improved battery management. Together, these updates highlight how community-driven firmware has become an essential layer in the modern retro handheld ecosystem, often unlocking capabilities far beyond the stock software.
Batocera 43 Update: New Devices, Smarter Emulation, Cleaner Interface
Batocera 43 is a substantial upgrade, especially for owners of newer Android-based handhelds. The firmware now supports the Retroid Pocket 6, AYN Odin 2 Mini, AYN Thor, PowKiddy X55, and several Anbernic RG “XX” devices, with some of these marked as initial support as the community continues to refine them. A key technical change is that SM8250 and SM8550 devices now share a single image, with device selection handled in the bootloader, which must be upgraded before moving to v43. Beyond compatibility, Batocera 43 tweaks its emulation stack and front-end. It replaces Azahar Plus with the original Azahar project, removes the closed-source DraStic emulator, and adds features to EmulationStation such as LED colour control, LED disable options, and multi-screen brightness control. Quality-of-life additions like a virtual keyboard for Wayland touchscreen devices and targeted bug fixes round out a release focused on polish as much as power.
KNULLI Scarab: A Massive Refresh with RetroArch 1.22.2 and Better Tools
KNULLI Scarab arrives roughly eight months after the previous major version and is described as one of the project’s biggest updates to date. It significantly broadens hardware coverage, adding support for more than 15 handhelds, including TrimUI Smart Pro S, Anbernic’s revised H700-based RG XX models, RG Vita Pro, RG DS, BATLEXP G350, GKD Pixel 2, Miyoo Flip, Powkiddy X55, and several Retroid devices such as the Retroid Pocket 5 and Flip 2. Under the hood, the firmware upgrades RetroArch to 1.22.2, improving core emulator capabilities and compatibility. A standalone Yabasanshiro emulator is now available for better SEGA Saturn performance. Utility upgrades are equally notable: improved Syncthing integration enables manual or automatic sync on game exit, BatteryPlus offers more precise battery state information, and new Silky RGB support enhances RGB lighting. Because of renamed paths and a changed SD card partition table, Scarab generally requires a full re-flash, though an advanced upgrade path is documented.
Performance, Quality-of-Life, and the Push for a Unified Experience
Beyond headline features, both Batocera 43 and KNULLI Scarab focus heavily on performance, stability, and streamlined user experience. KNULLI’s team emphasizes numerous bug fixes and improvements that benefit system stability, performance, and battery life, reinforcing its reputation as a reliable daily-driver firmware for retro handheld gaming. Batocera 43 addresses device-specific issues such as Wi-Fi problems on certain Odin 2 variants and fixes for MelonDS save and cheat paths, plus improvements to how PS4 and PS Vita titles appear in auto collections. Together, these changes reduce friction for everyday use: users can expect fewer quirks, better power management, and more consistent behavior across systems. The extra configuration options—like LED control, refined keyboard layouts, and better sync tools—also cater to enthusiasts who want to fine-tune their setups without sacrificing ease of use.
Expanding Retro Handheld Gaming Across Diverse Devices
Taken together, the Batocera 43 update and KNULLI Scarab firmware underscore a shared goal: bring robust, console-like retro experiences to as many handhelds as possible. Support for devices like the Retroid Pocket 6, AYN Odin 2 Mini, and a wide array of Anbernic and Powkiddy models means players can choose hardware based on form factor and budget, then rely on community firmware to handle emulation. Up-to-date emulator stacks, such as RetroArch 1.22.2 and focused additions like standalone Yabasanshiro, ensure that even demanding systems are more playable than before. At the same time, thoughtful touches—enhanced battery reporting, improved RGB control, and sync automation—show maturity in design. As these projects continue to iterate, they are steadily lowering the barrier to entry for retro handheld gaming and pushing the ecosystem toward a more unified, polished, and user-friendly future.
