Overview
- Delta released version 2.0 on Thursday, October 22, 2026, adding controller skins that adapt to every iPhone Duo pose and a fold‑to‑sleep feature that puts emulated Nintendo DS games to sleep when the Duo is closed.
- The app’s interface has been rebuilt for Apple’s Liquid Glass language so artwork and controls reflow across iPhones, iPads and both Duo displays while retaining split‑view multitasking through a custom keyboard view.
- Delta 2.0 adds native Sega Genesis compatibility with themed controller skins, RetroAchievements support, save states and cheat features to match the emulator’s existing options for older systems.
- The release includes a community‑built Pokémon DLC system for Game Boy Advance mainline titles described as coming soon and experimental support for Epilogue cartridge readers plus importable visual filters to change game appearance.
- Delta is shifting distribution by adding App Store in‑app purchases and debuting on the EU App Store while keeping Patreon support in some regions, a move that expands access but occurs in a legally sensitive area because ROM and DLC use rely on third‑party content and hardware.
