I've bought this game years ago and for some reason I thought it would be a good idea to run it, the thing is that there's no way I can record a run that for sure will last for 3 or more hours. I was thinking on maybe use my Lighting to HDMI cable to put the video on a TV and using another camera to record my TV, wound it be allowed?

I'm thinking of this because my iPhone is only 32 GBs and there's no way it can fit a 3+ hour screen record video. The Lightning to HDMI adapter provides no advantage and its purpose is to output my iPhone screen to a TV and I can use another camera (with more storage) to record the run.

I have no interface to output my iPhone screen to my PC (or even to my old Mac) to record the screen either. This idea I had it's my only choice for now unless I find some way to work around this.

You can use an Emulator like Bluestacks to play and run the game, but if you want to play on your mobile device I'd suggest asking either @WarMech or @Shiny as they both run PvZ 2 and will know more about recording on mobile.

Or try to do a Stream by the Twitch's App.

Thanks for the replies, I will check on that!
