Troubleshooting \ Additional Setup
Step 1: Download this .command file and place it somewhere that you won't move it, I chose the Applications folder since that's where I'm putting the app itself as well (the app will stop working if you move the command file). [Alternatively you can make it yourself if you want in textedit since it's just 2 lines of code]
cd zelda3
./zelda3
Step 2: Launch Automator and create a new application
Step 3: Drag the zelda3.command file into the box, then type open into the search box and drag "Open Finder Items" into the box.
Step 4: On the "Open Finder Items" section, select the "Open with" dropdown and choose "Other...", then scroll down to Utilities and select Terminal.
Step 5: Go to File, Save or Press Command+S and save the app wherever you want, I chose Applications. Make sure the File Format is an Application.
Step 6: The app will be saved but it will have the generic Automator Icon. To change it to whatever you want, right click on the app and choose "Get Info". Then, convert any image to an ICNS file and drag it on top of the Automator Icon to change it. Congrats, you're done and now have a .app file to run zelda3 with instead of manually having to use Terminal!
