Delta 2.0 Adds Sega Genesis Support, a Redesigned iOS Interface and Experimental Pokémon DLC

Delta, the iOS game emulator, has been upgraded to version 2.0. The Verge reported the release on October 22, 2026, describing an update that extends the app's system coverage, redesigns its interface, and adds several experimental features.

The most visible change is the interface. Delta 2.0 introduces a new UI built for Apple's Liquid Glass design language, and it adapts to all screen sizes across iPhones, iPads and the iPhone Duo. The library gains dedicated recents and favorites pages. Split-view multitasking now works alongside other running apps, so a user can keep a game on screen while working in a second app.

The iPhone Duo receives its own optimizations. Folding the device puts emulated DS games into sleep mode, in the same way that closing the lid of a physical DS suspends the hardware. The gesture-to-suspend behavior is a small detail, but it is the kind of hardware-aware state handling that separates a port, meaning software adapted from another platform, from a native implementation.

Controller handling has also changed. Delta creator Riley Testut said Delta 2.0 optimizes controller skins, the on-screen button layouts, for every pose in both portrait and landscape orientation. Skins are now animated, and the release adds a set of Sega Genesis skins for iPhone and iPad that recreate the look of the classic Genesis controller. Delta already shipped with default skins for every supported system, and users can customize the look and feel of the app through them.

Genesis support is the headline addition to the system list. Delta's existing lineup, which includes NES, SNES, N64 and DS, now extends to Sega's 16-bit console. The official Delta website describes the app as the all-in-one sequel to GBA4iOS, and version 2.0 continues that consolidation approach across more platforms.

The most unusual addition is a DLC feature for Pokémon. DLC, or downloadable content, is add-on material delivered after a game's release. According to The Verge, the DLC adds event items and rare Pokémon to classic Pokémon games, and it will support all mainline Pokémon titles released for the Game Boy Advance. The content was developed by the Pokémon ROM hacking community, meaning fans who modify the data of existing game files, and the developers did so without use of AI tools. That attribution matters for a feature of this kind, because the ROM hacking community has long built modifications on top of original game data, and the DLC sits in that tradition rather than in a licensed-content model.

Two experimental features extend the app beyond the screen. Delta 2.0 adds experimental support for Epilogue's GB/SN Operator gadgets, which allow players to run Nintendo cartridges on an iPhone or iPad. It also adds experimental Custom Filters, including a CRT-inspired default that imitates the scanlines of an old television, and support for imported filters. Both are labeled experimental, which signals that their behavior may change before they settle.

On distribution, Delta 2.0 is the first release to the EU App Store, which makes Delta available globally alongside AltStore PAL, an alternative distribution route for the EU. Patreon supporters gain a new route to in-app purchases through a Become a Patron option, now offered globally. The official website's earlier guidance pointed EU users to AltStore PAL and other users to the App Store listing.

In my view, the combination of a broader App Store footprint and a more capable UI is the more consequential change for the app's long-term position than any single system addition. A Genesis skin is a pleasant touch. A single app that handles multiple cartridge-era systems, adapts to foldable and tablet form factors, and reaches users through the official store gives developers and players a more predictable platform to build on.

The broader context here is less certain. Emulation sits in a legal and licensing gray area that varies by country, and the Pokémon DLC raises questions about how much of a classic game's content can be altered and redistributed. Users and developers will learn how these questions play out in practice over the coming months, as the experimental features move through testing.
