Jacare vs ROM Manager

Jacare has no write-up on Specifiction yet; its figures are above.

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.
