v0.2.0
839db57

Runs Beat Saber 1.44.1 as a native Windows ARM64 program under ARM64 Proton (tested on the
Steam Frame) instead of emulating the x64 build with FEX.

Works with
Proton proton-11.0-2c only: Steam's "Proton 11.0 (ARM64)" at that build
Beat Saber 1.44.1 only (Unity 6000.0.40f1), e.g. a BSManager instance
VR SteamVR (OpenXR)
Mods BSIPA 4.3.7 with Harmony mods (tested: SiraUtil, BSML, SongCore, BS Utils, CustomSabersLite, HitScoreVisualizer)

Check your Proton build before installing; it must print proton-11.0-2c (with an -arm64 suffix):

cut -d' ' -f2 ~/.steam/steam/steamapps/common/"Proton 11.0 (ARM64)"/version

The installer refuses any other Proton build, because the Steam and OpenXR libraries talk directly to
that Proton's own libraries. When Steam updates Proton, wait for a matching release.

Install

Easiest: the ARM64 tab of the Steam Frame BSManager fork
(https://github.com/DaVarga/bs-manager) installs this release for you. By hand:

Work on a copy of your 1.44.1 instance (BSManager can duplicate instances). The Wine prefix
must exist: launch any game with it once.

tar xf bs-arm64-v0.2.0-proton-11.0-2c.tar.gz && cd bs-arm64-v0.2.0-proton-11.0-2c
./bs-arm64.sh install ~/.local/share/BSManager/BSInstances/<copy>   # also downloads the Unity player etc.
./bs-arm64.sh launch  ~/.local/share/BSManager/BSInstances/<copy>
./bs-arm64.sh uninstall ~/.local/share/BSManager/BSInstances/<copy> # restores the x64 files

Without mod support: install --no-mods (engine only), or launch --no-mods to start one
time without mods. If you (re)install BSIPA afterwards, run install again. See docs/INSTALL.md for every file it
touches.

Known issues

  • If the headset goes into standby while SiraUtil restarts the XR session at startup, the game stays
    on a black screen. Keep the headset on while the game starts.
  • Burst code runs as managed code (no ARM64 Burst library). LIV capture isn't available.

Not included

The Unity ARM64 player, Unity's OpenXR plugin and Microsoft's VC++ runtime aren't redistributable. The
installer downloads them from their official sources. Corresponding source for the binaries:
SOURCES.md, built from https://github.com/DaVarga/bs-arm64/tree/839db57c45da69194908e4dbeb054e0665d15f01.
