Just played with Provenance today. Replaying some legacy games from my childhood! Recommended!!!
What is Provenance
Provenance brings together a collection of classic gaming console emulators into a single app for your iPhone, iPad or Apple TV, with support for Apple Game Controllers for that authentic experience.
Installation
You need to use Xcode to build and deploy this app yourself.
instruction
There are some downloadable compiled binaries online so that you don’t have to build it yourself. But I haven’t try it.
Quick youtube tutorial for that
ROMs
I’m using this site.
Upload ROMs
Open the app and click on the plus button top right. Keep the dialog open and visit 192.168.1.112 in your computer. You’re ready for uploading!
Controller issue
iPhone6 & iPhone6S users may have a problem for controller position
There is a pull request fixes this issue.
It’s not been merged at this time(2017-06-05). However, it’s a small fix with only a file. You can simply replace Provenance/Controller/PVControllerViewController.m with pull request version.
Happy gaming~~
