v1.1.0

latest

Released · 3 min read

v1.1.0 is the release where Retrace meets SN Operator. With Founder’s Edition now in people’s hands, we wanted the app ready for it, and this is that update. Most of what’s in here came from the email pile after v1.0.0 landed.

SN Operator support

Retrace works with SN Operator now. Plug it in over USB-C, drop in a SNES cartridge, and you get the same identification, pricing and authenticity flow you already had on the Game Boy side. SNES detection still carries a beta tag. The database is getting better with every release as we gather data from real cartridges, and a small number of less common titles won’t have a confident match yet. If yours is one of them, the unrecognised-cartridge form in the result panel goes straight to us.

Just plug it in

You no longer have to tap to start. Insert a cartridge and Retrace runs identification and authenticity checks on its own. Plug, insert, look at the result.

Tablet layouts

Layouts now scale on iPad and Android tablets. Before, the app rendered at phone proportions and left half the screen empty. That’s fixed. The Settings page, the result panel and the cartridge details all use the room they’re given.

A Settings page

There’s a Settings page now, reachable from the top of the app. It’s where preferences and app info live going forward, and where new options will land as we add them.

Smaller features

  • Haptic feedback. Buttons and key actions now give a small vibration on supported devices.
  • Writability on result labels. The result card tells you whether the cartridge is writable, which makes flashcarts and original carts easier to tell apart at a glance.
  • “Inconsistent Read” label. For cartridges that fingerprint as a flashcart but don’t read the same on every pass. Usually means dirty contacts. We recommend a clean before drawing any conclusion.
  • ROM size fallback. A handful of cartridges report a zero ROM size from the Operator firmware. Retrace now falls back to the size from our database in those cases, instead of giving up on identification.
  • Splash polish. The splash holds for at least one second so it doesn’t flicker on fast cold starts.

Behind the scenes

We added anonymous diagnostics through Sentry. Crashes and errors are tied to a randomly generated anonymous ID per session so we can correlate reports without identifying you. No personal data is collected. This is how we catch the long tail of issues that only show up on a specific phone, a specific OS version, or a specific cartridge.


Retrace updates automatically through the App Store and Google Play. Thanks for the emails after v1.0.0. A lot of this release exists because of them.
