Does this mean SCIRRA is no longer supporting Ejecta or the other way around?
Indeed Scirra stopped officially supporting Ejecta and prefer you to use the Cordova export solution.
So I think my best option would be to go back to release 191 (or 190 for a good measure ) and save my game there. Is this still an option for me?
I would not recommend such a downgrade.
You would lose all the workarounds made especially for iOS 9 in the most recent releases.
Ejecta + VMWare seems to be THE BEST OPTION for me as I don't have an i-Whatever device to test my game in.
So why try to publish to iOS since you can't even make sure your game is working ?
Nevertheless, Intel XDK provides you with some emulation device that could allow you to "virtually" test your application.
But it is nothing more than an emulator and not the actual deal.
