ROM Manager vs RomVault

ROM Manager is free, MIT-licensed software for organizing and converting retro console game ROMs. Its pipeline extracts archives, renames files using known game codes, converts ISO or WBFS images to CHD or RVZ, and cleans up files. It can create missing cue sheets for BIN tracks. Interfaces include a command-line tool, Python API facade, MCP server, and optional agent server with an AG-UI web interface. CLI and MCP tools can manage a self-hosted RomM library through its REST API using Basic or OAuth2 authentication. MCP tools cover conversion, game-code lookup and naming, and RomM resource groups, with environment toggles controlling domains. The server supports stdio, Streamable HTTP, and SSE transports; authentication is configurable, with none as the local default. Local conversion needs no service URL or credentials, while RomM access requires server details and credentials or a token. Conversion depends on external chdman and dolphin-tool binaries; extraction uses 7z or optional backends. Destructive cleanup can remove source files, so backups are advised.

RomVault is ROM management software for maintaining collections against DAT files on Windows and Linux. It scans ROMs, identifies available fixes, and rebuilds sets according to DAT definitions. Duplicate detection, file renaming, and hash verification are included. The built-in DATVault can update DAT files from ROM cataloging projects, although access without a key is limited to official MAME listxml DATs. Patreon supporters receive full repository access and a unique key. RomVault handles uncompressed files, ZIP, 7z, and CHD archives; RAR is not supported. The graphical interface runs directly as a standalone executable without an installer and needs write access to its directory. Separate command-line builds are available for Windows and Linux. Scanning and fixing default to Level 2. Removed files move to ToSort, with an optional double-check before deletion. The free plan costs nothing and includes core functionality without ads or nag screens.
