The SN Operator resembles a module slot for the computer: an original Super Nintendo or Super Famicom game is simply inserted and starts via the proprietary “Playback” software. An emulator is used, which is intended to provide the most authentic execution possible. The adapter is connected via a USB-C port and, according to the manufacturer, works on Windows, macOS, and Linux. This means that users of Valve's Linux-based handheld Steam Deck can also use it, for example.

Backup and authenticity check also possible

Epilogue's software also complements the classic gaming experience with modern features. These include cheats, achievements via the RetroAchievements platform, and convenience options such as fast-forwarding or manual save points. In addition to the actual games, Epilogue places great importance on data backup. Save games and complete game data can be transferred to the computer with just a few clicks. Saved game data should also be transferable back to the cartridge later.

Created ROMs can then also be played directly on the computer with emulators from other providers. This backup function could be particularly valuable for lovers of classic SNES games, as the save batteries used in cartridges can run out and save data can be lost as a result. A feature that is particularly important for collectors is the check for cartridge authenticity. Epilogue states that the device can distinguish original cartridges from fakes. It also monitors electrical parameters such as current flow and connection stability to ensure error-free reading.
