Delta iOS Game Emulator
Not long after the release of the original iPhone, it was "jailbroken", allowing for the installation of unapproved apps. One of the most popular among them was a game emulator. Over 15 years later, a legitimate option has finally appeared in the App Store: Delta. Developed by Riley Testut, it supports a wide swath of retro gaming console ROMs, including those for the NES, SNES, Game Boy, Game Boy Advance, Nintendo 64, and Sega Genesis. The on-screen controls switch automatically to match the ROM's original console, while features like wireless controller support, quick saves, Airplay streaming, and multiplayer make it even better than the originals in many ways. Available now as a free download.
