Last week, I powered on a 26-year-old copy of Pok\u00e9mon Pinball<\/em>, one of the best Game Boy games ever made. My save file was no more. The Charmander I\u2019d caught for my daughter<\/a>, the high scores we\u2019d set together\u2026 gone. Before flash memory, Nintendo cartridges used tiny watch batteries to save their games, and those batteries were never meant to last this long.<\/p>\n<\/div>\n

\n

But it\u2019s not a huge deal, because I saved<\/em> my family\u2019s save file months ago. I backed it up with an Epilogue Operator, a device that connects your real Nintendo cartridges to Windows PCs, MacBooks, even a Steam Machine.<\/p>\n<\/div>\n

\n

The $50 GB Operator<\/a> is a transparent trapezoidal cartridge reader that reads and writes to real Game Boy, Game Boy Color and Game Boy Advance cartridges over a USB-C cable; the company\u2019s new $60 SN Operator<\/a> does the same for Super Nintendo and Japanese Super Famicom titles. Epilogue\u2019s also got a N64 version coming.<\/p>\n<\/div>\n

\n

They\u2019re not just for backups! As you can see in my embedded video, these gadgets can play<\/em> your carts, too. My Xbox Ally now takes Super Nintendo cartridges, my Steam Deck plays Game Boy carts, and my phone is a Game Boy Camera, because I attached an Epilogue Operator to each one. (Double-sided magnet rings<\/a> and Mechanism mounts<\/a> helped.)<\/p>\n<\/div>\n

\n

Technically, the SN Operator and GB Operator are just cartridge readers, there are no original Nintendo chips or FPGAs inside. When you play a game, your computer saves the ROM to your computer and plays it in an emulator.<\/p>\n<\/div>\n

\n

But Epilogue\u2019s Playback software<\/a> makes that easy \u2014 just plug in the reader, plug in the cart, hit play \u2014 and it casts a convincing illusion that you\u2019re playing your games on actual carts. Plug one in, and your game pops up on screen. Whenever you save in the game, Epilogue should automatically save back to your cartridge as well. Whenever you yank a cart, the game instantly winks out.<\/p>\n<\/div>\n

\n

That last one\u2019s a bit of a double-edged sword, because Epilogue\u2019s Operators can be touchy about cartridge detection. They aren\u2019t as forgiving as an actual Super Nintendo or Game Boy if your carts are slightly dirty or damaged. I\u2019ve got Japanese copies of Bahamut Lagoon<\/em> and Sailor Moon R<\/em> that\u2019ll quit mid-session if I nudge them wrong.<\/p>\n<\/div>\n

\n

But I love that I can write savegames to my cartridges: I can play a game on my PC, move the cartridge over to my Steam Deck, then pop it into an actual original Game Boy or Super Nintendo and pick up where I left off. If you don\u2019t need to automatically write saves, you can even switch to an emulator core that offers RetroAchievements, plus optional creature comforts like saving anywhere in a game with save states, or the ability to rewind time and try that tricky jump once more.<\/p>\n<\/div>\n

Want to hear something especially nerdy? My family recently played Super Metroid<\/em> on the Super Famicom Classic Edition<\/a> that Nintendo released in 2017, and there\u2019s actually a way to pull your savegames off of those emulator consoles, too. I converted and wrote that savegame to my actual Japanese Super Metroid <\/em>cartridge, and now I\u2019m playing that save on 30-year-old original Nintendo hardware. (Speaking of: did you know a Japanese copy of Super Metroid <\/em>is downright affordable and entirely in English?)<\/p>\n<\/div>\n

(I attached the SN Operator with a Mechanism mount and some right-angle USB-C adapters.<\/em><\/figcaption><\/p>\n<\/div>\n<\/div>\n<\/div>\n
\n

I never had a Super Nintendo growing up, and I don\u2019t have a working Super Scope light gun or SNES Mouse now. But the SN Operator is also helping me play amazing games like Metal Combat: Falcon\u2019s Revenge<\/em><\/a> and Mario Paint<\/em><\/a> and share them with my kids, no crusty old peripherals necessary. There\u2019s an option to let your PC mouse cursor emulate a light gun or mouse, and it was simple to map those to my Steam Controller\u2019s<\/a> gyroscope aiming.<\/p>\n<\/div>\n

\n

While you can do most if not all of these things by pairing emulators with other hardware, including the Open Source Cartridge Reader<\/a> and a variety of Game Boy readers<\/a>, Epilogue\u2019s hardware is surprisingly high-quality considering its low cost, with attractive minimalist circuit boards clearly visible through classy polycarbonate. You know how we love our transparent gadgets<\/a> around here.<\/p>\n<\/div>\n

\n

And Epilogue isn\u2019t just riding on the coattails of emulator developers, either. While the hardware\u2019s proprietary, the Romanian company contributes some money<\/a> and some code<\/a> to open source emulators. Co-founder Petru Sebastian Toader also tells me he built his software\u2019s excellent <\/em>new CRT filter himself, the company\u2019s working on online multiplayer<\/a>, and every single SN Operator has its clockspeed factory-calibrated using satellites<\/em><\/a> so they can dump certain SNES games without errors<\/a>.<\/p>\n<\/div>\n

\n

Epilogue\u2019s also teamed up with the developers of Delta Emulator so you can plug real carts into your phone<\/a>, and even built its own Flashback app<\/a> if you want to turn your phone into a Game Boy Camera.<\/p>\n<\/div>\n

\n

With all these amazing features, I just think Epilogue should be a little bit more upfront on its product pages about the compromises you need to make.<\/p>\n<\/div>\n

\n

You should know the limitations: the Operators don\u2019t work with multi-game flashcarts, they don\u2019t work with the Super Game Boy, and their heavily marketed \u201cCounterfeit cartridge detection\u201d has been very hit or miss in my tests<\/a>, to the point I wouldn\u2019t really trust it. The company advertises that it can turn your Game Boy Camera into a webcam, but it\u2019s more of an OBS screen recording hack<\/a> than I would have guessed.<\/p>\n<\/div>\n

\n

And if you, like me, have original Game Boy cartridges with original batteries, it may be too late to save some of your saves by now. It\u2019s far too late to pull Pok\u00e9mon off second-gen games like Pok\u00e9mon Gold, Silver<\/em> and even Crystal<\/em>, whose real-time clocks drained their backup batteries and might not have lasted more than a decade.<\/p>\n<\/div>\n

\n

As for first-gen Game Boy games, I pulled a Charmander off an original Pok\u00e9mon Red<\/em> cart last year, but even those carts are reaching their battery\u2019s end of life. I have a 30-year-old copy of The Legend of Zelda: Link\u2019s Awakening<\/em> whose battery was working last month. Last week, I found its save, too, was gone. Thankfully, the GB Operator backed up my progress a few months ago.<\/p>\n<\/div>\n

\n

Now I just need to install a new battery, flash my save, and I\u2019ll be back in business.<\/p>\n<\/div>\n
