Valve has been quietly investing in emulation technologies for devices powered by Arm chips, laying the groundwork for a possible “STEAM MOBILE<\/strong>“.<\/p>\n

The information emerged after official statements from the company about the use of these tools in its new Arm-based device, the Steam Frame<\/strong> headset.<\/p>\n

While emulation support may seem natural following the announcement of the Steam Frame, one detail stood out: Valve not only uses the open-source emulator FEX<\/strong><\/a>, but was also responsible for starting the project and funding it from the very beginning<\/strong>.<\/p>\n

 <\/p>\n

Valve launched FEX and funded its development for seven years<\/strong><\/h2>\n

In an interview with The Verge, Valve engineer Pierre-Loup Griffais<\/strong> revealed that the company sought out specialists to kick-start the development of FEX, a key tool for running native Windows games on Arm hardware without the need for ports.<\/p>\n

\u201cWe talked to a few developers we knew would be ideal for this kind of initiative\u2014something long-term that required a very specific set of expertise. We worked to convince them to start the project and have been funding everything ever since,\u201d said Griffais.<\/p>\n

The information was reinforced by Ryan Houdek<\/strong>, lead developer of FEX, who thanked Valve for supporting the project \u201cfrom the start.\u201d Houdek explained that the company gave full freedom to build the emulator as an open and sustainable tool, useful not only for Valve but for the entire community.<\/p>\n

According to Griffais, the company began working on the idea of supporting Arm hardware as early as 2016. \u201cWe knew it would be almost ten years of work before we had something robust that people could trust to run their libraries.\u201d<\/p>\n

It\u2019s all collaborative, but many people forget that Valve and other companies are also helping important Android emulation projects.<\/h3>\n

We talked about this in a short right after the Steam Frame was announced:<\/p>\n
