dayum...I gotta look into that
You'll also need the app RAR to extract the files,
I suggest Files by Google to utilize the files,
JoiPlay has a main app and it has Plug Ins,
You'll need the RenPy plugin which is also on the Play Store.
You can keep it all on SD,
So if you use the Mega app like I do,
And have your download location set to SD,
You'll also be extracting to that folder to keep it in one place,
The extraction can be long depending how big the game is,
Anything bigger than 2.5GB wont launch the JoiPlay app will CTD trying to start it.
Utilizing the files is easy,
With Files just go to the folder everything is on,
Tap on the extracted files then on the .py file,
JoiPlay will pick it up immediately,
Enter the version number and tap Add,
Then go to the JoiPlay app tap on the game and Play.
If there's a wt or a patch,
Extract or move it to the Game folder within the extracted files,
WT mods most of the time have a content folder,
A game folder and the actual files that are the WT,
Only move the actual files.
Use RAR to do the extracting and moving,
RAR will give the option to Replace All,
The patch/mod files are replacing original game files with the same name,
RAR just makes it ezpz.
