Keen on M1

Recently I came across Commander Genius, which [..] let's just say is a way to play Commander Keen on modern machines.

Since I am on ARM64 Darwin, a bit of tweaking needs to be done to run this x86_64 solftware. Here my notes:

 

• You need Rosetta installed
• You need to install openssl for x86_64. To not conflict with Homebrew for arm64, install it in a separate directory.

Open a x86_64 shell: 

> arch -x86_64 zsh

Install homebrew in a different directory (I use /Volumes/1TBSSD/opt/homebrew-x86_64, choose what fits your need)

> mkdir /Volumes/1TBSSD/opt/homebrew-x86_64
> curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C/Volumes/1TBSSD/opt/homebrew-x86_64

> export PATH="/Volumes/1TBSSD/opt/homebrew-x86_64/bin:$PATH"
> which brew
/Volumes/1TBSSD/opt/homebrew-x86_64/bin/brew
> brew install openssl@3

• change line 3 of the install script as below

DYLD_LIBRARY_PATH=/Volumes/1TBSSD/opt/homebrew-x86_64/lib:$DYLD_LIBRARY_PATH ./CGeniusExe

That is it.
