star is an application that lets you play PC games on Android with the best performance possible. It lets you access your Steam, Amazon, GOG and Epic Games library on the go.

• Package: com.winlator.star
• Version: v1.2-REVAMPED (build identifier 7.1.4x-cmod, versionCode 20)
• Android SDK: compileSdk 34, targetSdk 28, minSdk 26 (Android 8.0+)
• Upstream lineage: Winlator → cmod → Bionic Nightly → Star → Star Bionic (Compose)

• Discord server

• Telegram

• Full Jetpack Compose UI. Every user-facing screen, dialog, drawer, and overlay has been ported off Java/XML to Compose + Material 3. This is the only Winlator fork to do this.
• In-game Compose overlays. Side drawer, settings dialogs, screen-effects panel, and task manager all run as Compose Dialog windows over the X server.
• Dynamic theme system. AppThemeState + ThemePreset allow live color/theme switching.
• Controller support restored to Star 1.1 parity. SDL2 SoName symlink wired into the Compose splash install path; all four controller event files pre-created at startup.
• Box64 dropdown bug fix. Edit-dialog now seeds the Box64 selector from the saved container value instead of resetting on dependency refresh.
• Bionic content pattern. Ships the larger container_pattern_common.tzst (bionic build, ~77 MB) for an expanded Start menu toolset.
• Adreno-tuned drivers bundled. SDK36 patched Turnip, AdrenoTools v819, and Wrapper variants (gamenative, leegao, legacy, original).

This project is built via GitHub Actions only. Local builds are not supported.

Artifacts are published as workflow artifacts; tagged stable builds are also published as GitHub Releases.
