Delta iOS adds cartridge support for Game Boy and Super Nintendo carts
Delta’s new Epilogue link turns Game Boy and SNES carts into something iPhone users can verify, back up, and actually play instead of just store.

Delta’s newest beta pushes the app closer to a preservation workflow that retro fans have wanted for years: physical carts are no longer just shelf pieces, but usable media that can move into a modern iPhone or iPad setup. Delta is already an all-in-one emulator for non-jailbroken iOS devices, and the new Epilogue-related feature folds real cartridges into that experience instead of forcing a separate desk-bound dumping setup or a full console chain.
The timing makes the update feel deliberate rather than incidental. Delta arrived on the App Store in 2024, added iPad support in July 2024, and now Riley Testut’s locked Patreon post, Delta 2.0b4: Redesigned Settings + Cheats & New Feature from Epilogue!, went up 20 hours ago, making this the clearest sign yet that the feature is moving through beta. Delta already supports Nintendo systems including SNES, Nintendo 64, Nintendo DS, Game Boy, Game Boy Color, and Game Boy Advance, so the new cartridge path fits squarely into the app’s existing pitch.

The practical workflow still revolves around Epilogue’s hardware, and that is where the preservation angle gets concrete. The GB Operator handles Game Boy, Game Boy Color, and Game Boy Advance cartridges, while the SN Operator is built for Super Nintendo and Super Famicom carts. Epilogue says Retrace, its mobile app, turns a phone or tablet into a cartridge companion, connects to an Operator device over USB-C or a local network connection, and returns release history, market pricing, developer credits, and authenticity verification. Retreace requires a GB Operator or SN Operator, which keeps this from being a software-only gimmick.

That hardware-first approach also explains why collectors may care. Epilogue says its tools back up save data, verify cartridge hardware, and detect counterfeit markers, and its support docs warn that software checks are fast and automatic but not a guarantee. For higher-value carts or anything uncertain, Epilogue still recommends physical inspection alongside the app check, and it notes that reproduction cartridges can behave unpredictably. Even so, the GB Operator page’s $49.99 price tag, its June 30 shipping date, and Epilogue’s 98.7 percent counterfeit-detection claim show a product line that is trying to bridge original media and modern playability, not replace one with the other.
