Ah I was sure I downloaded here. Will try download again - how do I transfer the save?
You have 3 options.
1. Drag the save folder from the old version into the new one (and overwrite if needed).
2. You can move individual save files instead, e.g. "file1", but you also need to move the "global" file as that holds the information about which save slots have data. The "config" file has your settings.
3. Make a new save in the new version in slot 1. Then transfer the old save you want such as "file5" to the new save folder and re-name it to "file1" after deleting the other "file1" you just made by saving in slot 1. This would give you the cleanest slate in terms of cleaning up old saves you may not be using.
