Installing

OpenSheep is one file, opensheep.wasm. It runs on gasm's runner, gasm-run, on macOS, Linux and Windows, or in the browser on this site's player.

A bundle

The easy way: a release bundle from GitHub, with the module, gasm-run and a launcher that asks for your CD once and remembers it.

System	Bundle	Start
macOS (Apple Silicon and Intel)	opensheep-gasm-<version>-macos-universal.zip	Sheep (gasm).app. It is signed ad hoc, not notarized: the first time, right-click it and choose Open. Hold Option while opening it to pick another CD.
Linux x86_64 / arm64	opensheep-gasm-<version>-linux-<arch>.tar.gz	./opensheep.sh (--install-desktop adds a menu entry). Needs ALSA and a Vulkan or OpenGL driver.
Windows x86_64	opensheep-gasm-<version>-windows-x86_64.zip	OpenSheep.cmd

Each launcher takes --help; anything after the CD goes to gasm-run. The README inside says where the saves and the log are.

By hand

The runner

Download gasm-run 0.16.0 or newer for your system from gasm's releases. From a checkout of OpenSheep, tools/fetch-gasm-runner.sh <platform> does it for you and prints the folder it unpacked to (platforms: macos-universal, linux-x86_64, linux-arm64, windows-x86_64).

The module

opensheep-<version>.wasm is attached to every release; or build it.

Running

gasm-run opensheep.wasm --asset cd=Sheep.iso          # a disc image
gasm-run opensheep.wasm --asset-dir /Volumes/SHEEP    # the disc, or a folder copy of it

See Game data for what the disc has to be. The settings, save slots and best times are kept in the runner's storage for the module.
