Install

Unpack the release and run install.sh from its folder, with the game closed.

CrossOver

./install.sh --crossover "<bottle>" sets up one bottle and leaves CrossOver.app as it is. The bottle gets its own copy of CrossOver's files in ~/Library/Mullion/Bottles/<bottle>, made of links, with Mullion in place of DXMT, and its graphics are set to DXMT. Run it again after a CrossOver update. If CrossOver.app is not in /Applications or ~/Applications, give its path as a third argument. To undo, put back the bottle's cxbottle.conf.before-mullion.

Wine

./install.sh <wine> [prefix ...] copies the libraries into <wine>/lib/wine, where they replace Wine's own Direct3D, and into each prefix named. <wine> is the folder that holds bin/wine. Prefixes made later need nothing.

By hand

The release has DXMT's layout, x86_64-windows and x86_64-unix. In CrossOver, rename CrossOver.app/Contents/SharedSupport/CrossOver/lib/dxmt to dxmt-original, put the release folder in its place under the name dxmt, and set the bottle's graphics to DXMT. In Wine, copy both folders into <wine>/lib/wine, and the DLLs of x86_64-windows into drive_c/windows/system32 of each prefix.

First launch

If macOS blocks winemetal.so at the first launch, allow it under System Settings, Privacy & Security, and start the game again.
