The few new games I tried in the last month are the ones that did not seem to save even though it said they did at the time whereas all my old ones occasionally come back with a lot of patience.
I don't know what happened in the month of August that caused this to happen but it appears saving is no longer option and I can no longer recover any of the data from those games.
Interesting, I cannot make new saves with the old games whose save data I recently recovered.
