SD card manager for retro handhelds

See and manage your handheld's SD card.

Plug in a Miyoo, Anbernic, or RG handheld and RetroBridge reads the card: every game, save, and system on it. Add games, remove the ones you're done with, build collections, and copy them back. It identifies games by their contents, not their filenames, so it recognizes them even when the files have odd names.

Features

What it does.

The things you'd otherwise do by hand in a file manager, in one app. None of them overwrite a save without backing it up first.

SEE

See what's on the card

Plug in and RetroBridge lists the systems, games, saves, and free space. It checks each game by hash against the No-Intro and Redump databases, so the filenames don't have to be right.

COLLECTIONS

Build collections

Group games into a collection and RetroBridge writes it in your firmware's own format, so it shows up in the handheld's menu. Nothing to install on the device.

FOCUS

Sync a set to the card

Focus mode adds the games that are missing and removes the ones that aren't on the list, in one pass. It backs up saves first, and you can undo each step.

SETTINGS

Carry settings between cards

Per-game emulator settings and shaders can travel inside a collection and apply to another card. Private values are removed before anything leaves your machine.

WI-FI

Connect over Wi-Fi

Browse, identify, and plan over FTP or SFTP without a card reader. Writing to the card still needs a cable.

VAULT

Back up saves

When you open a card, RetroBridge copies each save to a Vault on your PC and matches it to its game by hash. A dot shows whether each one is backed up, in sync, or out of sync.

Collections & sharing

Share collections as a link.

A collection is a list of game fingerprints, not the ROMs, so nothing copyrighted is shared. Send someone a link and they can see which of the games they already have and which they're missing.

Your collections stay yours to edit. If someone changes one, they get their own copy that still credits you. You can also browse what people have posted in the gallery.

Saves

It backs up before it writes.

Losing a save is the worst thing an app like this could do, so RetroBridge backs up before it writes and keeps a way to undo. That's what makes it safe to add and remove games. Every write goes through the same steps:

Reading can't write

Browsing, identifying, and planning can't change the card. Only the sync step writes to it.

It keeps restore points

Anything removed or overwritten is copied to your PC first, and one click puts it back.

Tested for failures

The test suite pulls the cable mid-sync and checks the card comes back unchanged.

Compatibility

Works with your firmware.

RetroBridge detects which custom firmware a card runs and adapts to its layout. Each firmware is a small data profile, not code, so new ones can be added without an app update, and you can write one yourself if yours isn't covered.
