Highlights

Additional metadata

The edit dialog now allows you to manually set metadata properties that would otherwise only be aggregated from metadata sources, if those metadata sources don't support/populate certain fields. [#2848]

Enhance folder structure config

We've improved the web interface that lets you configure platform bindings and versions, and excluded files and folders. This change should simplify the process of configuring how library folders are interpreted and what content is ignored during scanning. [#2809]

Patcher.js

  • We're introducing a new ROM patching feature to the app that enables your admins and editors to apply various types of patches to ROM files. At this time both ROM and patch files must be downloaded locally and re-uploaded via the patcher, with future work planned to patch ROMs directly from your library. [#2787]

UI settings sync

UI settings are now synced between devices for every user! These settings do not affect third-party apps, and any setting must be changed at least once for this sync to take effect. [#2777]

BIOS file defaults

A default BIOS file can now be specified per emulator core directly in your config.yml:

:::yaml
emulatorjs:
  settings:
    mgba:
      bios_file: gba_bios.bin
