Trying to install the Gamemaker module, but failing

[GetKeyOpenDoor]

I've followed the steps as described here
https://github.com/RetroPie/RetroPie-Setup/wiki/GameMaker-Games
Copy-pasted the script exactly.

But when I got into the Retropie setup, it flashes this error message shorty before entering the blue screen.
line 2: $'\r' : command not found
line 11: $'\r' : command not found
line 16: $'\r' : command not found
line 17: syntax error near unexpected token $
line 17: 'function install_bin_gamemaker() {

You have created a file with windows line endings - use an editor where you can save with LF (unix) line endings, or convert the file with dos2unix on the pi.

@BuZz Never knew about that, would opening and saving in nano also work?

I don't think that will help.

@BuZz I thought maybe because nano is a linux text editor it would auto convert EOL.
But anyway, there is an option in notepad++ for EOL conversion so I've just set it to UNIX. I'll give it a try after Kodi is done importing my library.
Thanks for the help
