Valve's Arm SteamOS Reaches Android Handhelds Through Developer Ports

The Steam Frame headset runs on an Arm-based Snapdragon 8 Gen 3 chipset, Android Authority reported, describing it as a VR headset powered by phone internals. The Arm release of SteamOS followed that launch, and developers hashtagbasit and MaSieS4Fun ported the Arm flavor of SteamOS to Android handhelds.

The port can run from a microSD card, so users do not need to wipe their device's internal storage simply to try it. Supported devices include the AYN Odin 2 family, the AYN Thor, the Retroid Pocket 6, and the AYANEO Pocket ACE, DS, EVO, DMG, and S 2K consoles, according to the report.

The process requires installing the Rocknix ABL first, which Android Authority called the most complex step. The reviewer had already installed the Rocknix ABL while trying Rocknix earlier in the year, so the remaining steps involved unzipping the SteamOS image and writing it to a microSD card with the Rufus utility for PCs. The MaSieS4Fun variant booted without issue on the AYN Odin 2 Portal, and the setup process worked.

In limited testing, Prodeus worked out of the box with playable but variable performance, Android Authority said. Mixed performance in general could be partly attributed to the games and the operating system running from the microSD card. Baba Is You and Geometry Wars 3 worked after switching to a different Proton version. Pac-Man Championship Edition DX and Spelunky 2 did not boot at all after trying different Proton versions.

Android Authority said others might have better results with more comprehensive configuration tweaks or different games, but it tentatively argued that most people interested in playing Steam games on Android are better served for now by apps such as GameNative, GameHub, and Winlator Ludashi. GameNative in particular offers a known configs option that automatically applies the best settings for each game.

Android Authority described the ability to run SteamOS on an Android handheld as impressive. The report said that even if Valve does not plan to officially support these handhelds soon, the work suggests groundwork is being laid for an eventual Arm-powered Steam Deck. It added that Valve will undoubtedly continue working on SteamOS for Arm to iron out kinks and improve game compatibility, and advised keeping an eye on the unofficial SteamOS ports.
