Not so, game freezes on joiplay when trying to save or load
I figured out how to completely fix the JoiPlay save/load freeze issue.
1. Go into the game folder and into the "www" folder. Look for the "save" folder.
2. Completely delete the "save" folder and everything inside.
3. Create a new empty folder in the same spot called same thing, "save".
That should fix it for you and make it instant. For whatever reason, the preexisting files and saves in that folder make the game freeze/lock and deleting it completely fixes the problem. The files in there are preexisting saves to allow u to skip the intro but theres no need for them if they break the game on Joi. Also I tried the suggestion to wait for the save to eventually load and it never did 30 mins later, so that's not a realistic solution. Best to just completely fix it by making a brand new save folder.
If for some reason that doesn't completely work, there's 1 other thing I did before fixing it.
1. Hold press on the game icon in JoiPlay and hit "Edit Plugins"
2. Find the plugin called "save extra info" or something like that and disable it
