ABL Dual Boot: Switch Between Android ⇄ Linux on Gaming Handhelds with a Single Tap

⚡ The gist in 5 seconds - The ABL Dual Boot project has been released: one-tap switching between Android and Linux on handheld gaming consoles. - It works via the ROCKNIX bootloader and includes an Android app with a Quick Settings tile, a Decky plugin, and a Linux script. - Requires a device with the ROCKNIX bootloader — it won't work with other bootloaders. ### 🔍 What was found On GitHub, the kingsleydon/abl-dualboot project was published — a tool for one-tap switching between Android and Linux on handheld gaming consoles that use the ROCKNIX bootloader. The project is distributed as an open repository. The solution consists of three components: an Android app with a Quick Settings tile, a Decky plugin for the Linux side (Decky is a popular plugin loader in the SteamOS/PortMaster ecosystem), and a Linux script. This means switching is available from both systems: on Android via the Quick Settings shade, and in Linux via the plugin or script. ### 💡 Why it matters Owners of Android-based handheld consoles (devices like Retro Handheld) often install a second OS — Linux distributions like ROCKNIX — for better emulation, but rebooting and choosing a system through the bootloader menu is inconvenient. ABL Dual Boot solves exactly this problem — switching without long button holds or navigating the boot menu. The project is open source, with the code available on GitHub, so the community can adapt it to other devices.
