The modding community is repurposing Android-based gaming handhelds by installing SteamOS. This shift is driven by the release of a SteamOS port for the ARM64 architecture, which allows devices to run desktop-grade gaming software instead of being limited to Android titles.
Projects like Armada facilitate this transition for hardware from manufacturers including Ayaneo, Ayn, Retroid, and Konkr. These handhelds utilize mobile SoCs from Qualcomm and MediaTek, which now feature sufficient CPU and GPU performance to support desktop operating systems.
The technical foundation for this development stems from Valve's work on the Steam Frame VR headset, which is powered by the Qualcomm Snapdragon 8 Gen 3 platform. Valve ported its Proton 11.0 compatibility layer to ARM to support the headset's software environment.
Although Proton 11.0 was originally intended for the Steam Frame, its availability has enabled broader compatibility with other ARM-based devices. This allows users to run games originally designed for x86 architecture on mobile hardware that was previously restricted to Android.
