I have an iPhone 4 running the latest iOS for that - iOS 7-something. I want to install RetroArch for my iPhone, and I cannot seem to figure out how. Can someone give me step-by-step instructions on how to do this?
I do not know how to do it without jailbreaking and most cores don’t run that well on my old IPhone 4, but if you do want to jailbreak you can just download the pangu 7 tool here: http://en.7.pangu.io and jailbreak you’re IPhone 4 by connecting it with a computer, running the JB tool and following the steps. Once you’ve jailbroken the IPhone you can go to cydia, sources and tap the plus icon, then just add this link: https://buildbot.libretro.com/repo/cydia/
You’re welcome
There are lots of tutorials on youtube for that.
