Hey - I'm more than happy to test, but where is this Contents folder located? Or do I just create that folder in the same place where the saved games are stored?
No, the Contents folder is in the "app" file. This file can also act as a folder, if you have the right program to open it! On Windows I used 7zip to do it, but that program is exclusive to Windows, so you'd need to look for an "archiver" program that runs on your operating system. I don't have any recommendations for that I'm afraid.
