There aren’t many of them yet, and installation takes a little work (Apple doesn’t allow add-your-own-ROM emulators in the App Store), but new capabilities introduced in iOS 9 and the iOS-based tvOS make it possible to install them. One of my projects was to experiment with classic console emulators on the new Apple TV. That makes it a great time to tinker with little tech projects, things that are inessential and maybe a bit time-consuming but fun enough and useful enough to be worth doing. For those of us fortunate enough to have the privilege, late December and early January bring two things: new toys and a bit of vacation time.
