Delta’s gaming emulator has received a major upgrade, adding a host of new features and expanding its compatibility list. The most noticeable change is the optimization for Apple’s iPhone Duo, a foldable device that already resembles a Nintendo DS in shape. With Delta 2.0, users can expect smoother performance when running DS titles on the Duo’s dual screens.
Beyond the Duo support, the update introduces Sega Genesis titles, animated controller skins, and custom Pokémon DLC experiences. A refreshed user interface has also been rolled out, designed to work with the app’s Liquid Glass rendering mode.
Riley Testut, the creator of Delta, explained to The Verge that the new version “optimizes controller skins for every pose in both portrait and lands …,” highlighting the attention given to every possible orientation on the foldable phone.
Overall, Delta 2.0 aims to make the iPhone Duo feel like a natural handheld for classic games, while also offering fresh content and visual upgrades for longtime fans.
