Same here @chirpy43.  Plenty of Angry Birds .apk files available on (for example) Uptodown, all for free. But you do need a PC with a bit of RAM for those emulators to run smoothly.

Hi @chirpy43 I don’t know much about backing up .lua files but you seem to have that covered.If you have access to a PC I would recommend installing an emulator like Nox or Bluestacks.Have been able to install and successfully play even very old versions of Angry Birds(2012 onwards).
