GameNativeX64

Availability: GameNativeX64 ships on Bass: Lineout x86_64 builds that enable the gamenative addon (--gamenative). It targets Intel and AMD Android tablets and desktops (ax86), not ARM handhelds.

GameNativeX64 is the Bliss-Bass fork of GameNative. Upstream targets ARM64 and uses Box64/FEX translation; this fork runs native x86_64 with Mesa Vulkan (ANV/RADV) and adds Linux desktop app integration for Bass tablet deployments.

What it does

  • Runs Steam, Epic, and GOG PC games through Proton/Wine on x86_64 Android - no ARM translation layer

  • Uses hardware Vulkan where the device Mesa stack allows (Intel ANV, AMD RADV; lavapipe as software fallback)

  • Ships a guest Vulkan payload in-APK (~50 MB compressed; extracted on first launch)

  • Linux apps - install Debian packages inside a PRoot rootfs, launch GUI apps in per-app freeform windows, pin them to the app drawer via lightweight stub APKs

  • Frame generation - LSFG-VK (Lossless Scaling) on Intel and AMD Mesa, experimental on x86_64 (Bionic containers only; needs Lossless Scaling from Steam)

  • GPU present path - DRI3 dma-buf zero-copy presents on x86_64

  • Linux job engine for the Linux Services system addon: boot-started, scheduled, and auto-restarted Linux services, terminal programs, and GUI apps

Linux environment

The Linux environment is an Ubuntu rootfs (about 1.2 GB) that GameNativeX64 downloads once and runs under PRoot. Set it up from GameNativeX64's Terminal screen, from Linux Terminal in the app drawer, or from the Linux Services settings card when that addon is on the image.

Area Behavior
Display backend Android X (native X server with DRI3) is the default for freeform Linux apps. Xtigervnc is an opt-in compatibility fallback. Both are under Linux display backend in settings
Windows One freeform task per Linux app, titled with the app's name. The X screen follows the window size, so GTK and Qt apps reflow when you resize
Sizing App size scales Linux apps relative to Android's own UI (applies when a session next starts). App UI size scales GameNativeX64's own library and settings screens
Closing apps When a Linux app is closed: close the session, or keep it running so reopening is instant
Browsers Firefox installs from Mozilla's APT repository (Ubuntu's snap stubs do not work under PRoot). Sound goes through the same PulseAudio bridge as games, AAC decodes through the system ffmpeg, and Widevine/EME is on by default (Firefox downloads the CDM on first use)
App drawer With the stub installer on the image, Linux apps and installed games are published to the Android app drawer automatically, including after apt installs from the terminal. Removing an entry stops it from coming back until you add it again
Reset Linux Apps → trash icon (Reset Linux environment) deletes the rootfs and everything installed with apt

Installing the APK standalone

For sideload or testing outside a Bass image, download app-modernX64-release.apk from the GameNative-x64 releases page. Requires an x86_64 device (API 26+).

adb install -r app-modernX64-release.apk

The first game or Linux session start takes longer while the Vulkan payload unpacks.

Bass: Lineout image integration

Licensed Lineout workspaces enable GameNative at build time:

./build.sh --gamenative
# or
USE_GAMENATIVE=true

The build downloads a CI-signed release APK (tagged v*-x64.* on GameNative-x64) and preinstalls it on first boot. A privileged stub installer (app.gamenative.stubinstaller) is built from source in the image so Linux app drawer entries can be added and removed without per-install user prompts.

Release images must use the CI-signed APK and the release caller certificate list. Dev images may use --gamenative-dev-key for local Gradle builds; do not ship that configuration to customers.

See Addon Development: Bass Lineout for how Lineout addons are wired.

Fork highlights (vs upstream ARM64)

Area Upstream GameNativeX64
CPU Box64 / FEX Native x86_64
Vulkan Vortek ARM proxy Mesa ANV / RADV
Linux apps - Session manager, per-app windows, drawer stubs, Android X display
Linux jobs - Job engine for Linux Services (LinuxJobService)
Build flavor arm64 modernX64

Current release series: v1.2.0-x64.* (see GitHub releases for versionCode and notes). Linux Services needs v1.2.0-x64.17 (versionCode 152) or later.
