Delta has rolled out version 2.0 of its retro game emulator, introducing native optimizations for Apple's first foldable smartphone, the iPhone Duo. The milestone release is available worldwide on the App Store and through AltStore PAL in the European Union, arriving just as customers begin receiving the new foldable hardware. [1][2]
The update adapts Nintendo DS emulation to the folding format by placing primary gameplay on the upper portion and touch controls on the lower screen. Delta spans the fold in portrait book mode, reflows to fit the closed outer display, and automatically puts virtual DS consoles to sleep when users close the device. When used in landscape split-view mode alongside a video or another app, Delta circumvents standard screen constraints by exposing the bottom controller as a custom keyboard view that stretches across the full display width.

Beyond foldable hardware integration, Delta 2.0 introduces a Liquid Glass interface design, native Sega Genesis support with cheat codes and save states, RetroAchievements compatibility, and audio mixing with background podcasts or music. Early reviews of the iPhone Duo noted limited third-party app support, making Delta's deep hardware integration an early showcase for the foldable device. [1][2]
