Valve has open-sourced Lepton, its Android compatibility layer designed to run Android games on Linux within containers, primarily to support VR titles on its Steam Frame device. Lepton combines code from several open-source projects and is split between MIT and GPL-3.0 licensing, enabling developers to build and inspect the compatibility layer ahead of Steam Frame's shipment.

This Wire brief sits within Fusion42's coverage of Gaming Tech.

◆ ◆ The Wire takeaway

You can now build or integrate Valve's Android game compatibility layer into your Linux gaming projects this week. This lowers the barrier for Android game developers to reach Linux users, especially on Steam Frame hardware.
