We are proud to announce that Retrace is finally here! Although this might come as a surprise, behind the scenes we’ve been working on it for a while now, and today this new app is officially available to the public. Retrace is a companion mobile app for your Epilogue Operator that brings cartridge identification, market pricing analysis and counterfeit detection straight to your phone. Whether you’re at a convention, a yard sale, sorting through the latest haul or meeting up with a seller, Retrace is a must-have.
Cartridge Identification
Plug in your Operator over USB-C, insert a cartridge, and watch Retrace identify it in mere seconds. You get info about the game title, region, publisher, developer and all the metadata you’d expect. The entire game database is bundled with the app, so identification works offline as well, no internet required. Cover art and descriptions are pulled in when you’re back online.
Market Pricing
Once a game is identified, Retrace shows you current US market values so you know if you’re about to buy a diamond or a lump of coal. Pricing data is provided for informational purposes and reflects the latest market trends. It’s a helpful reference whether you’re buying, selling, or just curious about your own collection.
Counterfeit Detection
This is the founding principle of Retrace: instant counterfeit detection anyplace, anytime. Not sure what you’re looking at? Simply insert the cartridge, then the app runs in-depth analysis for known counterfeit markers and gives you an instant authenticity result. It’s the same detection technology from the GB Operator, now available on the go. Keep in mind that Retrace is an informational add-on tool and not a substitute for physical inspection. We recommend combining these two verification methods: Retrace first, then visually check what lies inside the shell for confirmation. Always inspect circuit boards against known reliable sources when making high-value purchases.
Works With All Operators
Retrace works with both GB Operator and SN Operator. Just connect over USB-C and you’re good to go.
Available on iOS, iPadOS and Android
You can grab Retrace from the App Store and Google Play. This first release is marked as Beta. Why? Well, everything works, but we’re actively improving the app based on real-world usage and feedback along the way. If you run into anything, shoot us an email and we’ll take care of it.
Retrace is the natural follow-up to Playback, our desktop app for Operator devices. And just as Playback today looks much different than when it first launched, we’re equally as excited to see where developing Retrace will take us.
