4. Making a CUSTOM JOIPlay Plugin (Advanced)

If you need saving, file access, or toast notifications, you can create a JavaScript plugin that JOIPlay can call.

Plugin Structure

Create a .jslib file in Assets/Plugins/WebGL/:

// MyJOIPlugin.jslib
mergeInto(LibraryManager.library,
Joiplay_ShowToast: function (messagePtr) 
var message = Pointer_stringify(messagePtr);
if (window.JOIPlayToast) 
window.JOIPlayToast(message);
 else 
console.log("[JOIPlay] Toast: " + message);

Joiplay_SaveString: function (keyPtr, valuePtr) 
var key = Pointer_stringify(keyPtr);
var value = Pointer_stringify(valuePtr);
if (window.JOIPlaySave) 
window.JOIPlaySave(key, value);
 else 
localStorage.setItem(key, value);

);

Step 1: Install JoiPlay First

Run the JoiPlay APK installer. Open the app once. It will ask for storage permissions. Grant them. This creates essential folders on your internal storage: JoiPlay/ and JoiPlay/unity/.

10. Alternative: Using Exagear + Wine (Legacy)

If your Unity game absolutely refuses to run on JoiPlay’s plugin, the only remaining Android option is Exagear Windows emulator + Wine – but that requires a powerful device and is no longer officially supported.
