Retro game emulator Delta looks great on the iPhone Duo

The retro game emulator Delta has recently released an updated version 2.0 that boasts a renewed Liquid Glass interface, along with support for the iPhone Duo. The app comes equipped with specially designed controller skins that cater to various iPhone Duo poses, such as Nintendo DS layouts that utilize the entire inner display and gracefully adapt to the crease when in book mode portrait.

The larger screen of the iPhone Duo facilitates immersive gaming experiences, while Delta ensures seamless reflow on the portrait closed outer screen as well. A hidden feature allows folding the Duo closed to automatically put the DS to sleep, mirroring the behavior of a real DS console.

An interesting aspect comes into play when using Delta in landscape split view alongside another app. In this configuration, the app reveals the bottom half of the virtual DS as a custom keyboard view, allowing the system to stretch it across the full width of the screen, overlapping an unrelated video player app on the opposite side of the split.

Delta's new update also introduces Sega Genesis ROM compatibility, enhanced library navigation, customizable audio settings that blend game audio with currently playing music or podcasts, and more.

The premium version of Delta can be accessed via an In-App Purchase subscription directly through the App Store, now available globally. In the US, EU, Brazil, and Japan, users can also contribute to the app's development via Patreon. For further Apple news, viewers can check out 9to5Mac on YouTube.
