# Foldable Retro Emulators Delta Turns IPhone Duo into a DS Handheld By Amy Duong | Written with AI assistance | Published 2026-10-26 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/foldable-retro-emulators-trend References: [notebookcheck.net](https://www.notebookcheck.net/Huge-update-Emulator-turns-iPhone-Duo-into-Nintendo-DS-adds-Sega-games.1432969.0.html)  Delta 2.0, the iOS emulator, adds support for Apple’s foldable iPhone Duo, letting [retro gaming fans](https://www.trendhunter.com/trends/ayaneo-pocket-micro-2) run [Nintendo DS titles](https://www.trendhunter.com/trends/the-miyoo-mini-flip) on a phone-shaped layout with one game screen on each half. Delta has logged more than 20 million downloads in about two years, and the update also adjusts touch controls to the hinge position and pauses DS play when the handset closes. On regular iPhones and iPads, Sega Genesis support brings another major console library into the app, and RetroAchievements adds goal tracking to older games that originally lacked it. Those two additions reduce the need to juggle separate emulators or settle for bare-bones ROM playback. Support for Apple’s foldable iPhone Duo turns a niche phone shape into a clearer gaming use case than split-screen multitasking alone. Delta’s 20 million-download base also widens the audience for that idea, because one emulator now spans both standard iOS devices and Apple’s new form factor.
