Data Manager

One place to manage everything that isn't a save: profiles, ROMs, sprites, languages, and music. Open it from the title bar → Data.

Tabs

Profiles

List, create, select, and delete profiles. Creating one binds a ROM, a language, and an optional MSU-1 pack.

ROMs

Import a ROM from a file or URL, view its info such as filename, size, hash, and timestamps, run asset extraction, and delete ROMs. Extraction status is shown per ROM.

Sprites

Per-ROM sprite extraction and management. Extract and cache sprite PNGs, review individual sprites, and inspect the item-to-sprite mapping. See Sprite Tools.

Languages

Extract translations from a ROM, a file, or a URL and manage language packs such as English and French. The selected language drives in-game dialogue.

MSU Studio

Import MSU-1 music packs from a file or URL, then build and edit them: every music slot, the ambient beds and both effect channels, each with layers you can shape. Manage the pack's audio files and convert them to one format. Attach a pack to a profile to replace the original soundtrack.

Where it lives

Each tab is backed by an Electron IPC domain: roms, assets, sprites, languages, msu, and profiles. The renderer never touches the filesystem directly. See Electron & IPC.
