Not working in Silicon Mac (Nine Sols, possibly other native games)

[pedroh77]

I have a MacBook Air M1 (2020). The game is Nine Sols. When I launched the script in the terminal I got a bunch of messages related to needing an ARM library, but it only has x64.

This is not hard to fix. You need to put a libdoorstop_arm64.dylib file inside doorstop_libs (I had to compile it though). Also, you have to modify this case statement in run_bepinex.sh to accomodate for the ARM64 case:

case $executable_type in
PE32)
echo "The executable is a Windows executable file. You must use Wine/Proton and BepInEx for Windows with this executable."
echo "Uninstall BepInEx for nix and install BepInEx for Windows instead."
echo "More info: https://docs.bepinex.dev/articles/advanced/steam_interop.html#protonwine"
exit 1
;;
64-bit)
# Detect if we're on macOS ARM64
if [[ "$os_type" == "Darwin" ]] && [[ "$(uname -m)" == "arm64" ]]; then
arch="arm64"
else
arch="x64"
fi
;;
32-bit|i386)
arch="x86"
;;
*)
echo "Cannot identify executable type (got ${executable_type})!"
echo "Please create an issue at https://github.com/BepInEx/BepInEx/issues."
exit 1
;;
esac

Also, at least in the Nine Sols release page you mislead MacOS users when you say:

"Steam Deck/Linux/MacOS Additional Instructions

You do not need to do this if you are using Windows!

Open up the game properties in Steam and add WINEDLLOVERRIDES="winhttp=n,b" %command% to the launch options."

This is bad for Mac, as trying to launch the game afterwards fails and the user gets an "OS error". WINEDLLOVERRIDES is a variable to be used for Proton, a Linux only software (and the MacOS package you distribute doesn't even have a winhttp.dll file anyway).

Rather, I went with "/Users/[NAME OF USER]/Library/Application Support/Steam/steamapps/common/Nine Sols/run_bepinex.sh" %command% as command line option, which works, since your script takes the game as argument.

Long story short, your mod works in Apple Silicon, but it requires, in the very least, adding libdoorstop_arm64.dylib to the package and modifying the launcher script code, otherwise no one who bought a Mac post-2020 is going to get your mod to work. Also remove the misleading environment variable for the command line from the instructions, the game won't launch with it.

The GitHub issue highlights compatibility issues of the game Nine Sols with Apple Silicon Macs (like the M1). The user reports encountering errors due to the absence of an ARM64 library and the use of misleading instructions related to a Linux-specific environment variable (WINEDLLOVERRIDES). They resolved the issue by compiling a missing libdoorstop_arm64.dylib library, placing it in the appropriate folder (doorstop_libs), and modifying the run_bepinex.sh script to detect and handle ARM64 architecture. They also point out that the instructions provided for Mac users about setting a Proton-specific environment variable are incorrect and prevent the game from launching. Instead, they suggest modifying the launch command by directly referencing the run_bepinex.sh script. The user recommends adding the ARM64 library to the package, updating the launch script, and correcting the documentation to ensure the mod works for post-2020 Apple Silicon Mac users.

The script and most of the package is from BepInEx, which can be found here https://github.com/BepInEx/BepInEx

Can you share the full SH and libdoorstop_arm64.dylib? I still think you should post this as an issue for BepInEx directly so that it is fixed at the source.
