Are there any good emulators on the app store? There was a discussion on some Commodore 64 app on Touch Arcade earlier, so I hoped more apps like it were being made.
Commodore 64, Intellivision (though there is debate if these are really emulated, and the controls aren't very good) and Chip8 are the only ones I know of that are confirmed legal and licensed. (Well, Chip8 and all its games are freeware, no license required.) There have been a few that have passed through the App Store that got pulled for one reason or another. ZX Nostalgia was a pretty good Spectrum emulator that contained over a dozen games, but none of them licensed, so it got pulled. There was a crappy Spectrum emulator that was an unlicensed port of a crappy Java one that also allowed you to side-load snaps. And the infamous Nescaline, which also allowed side-loading. Manomio and Kiloo will becoming out with a legal, licensed Amiga emulator soon.
