Daijishō vs RetroHub

Daijishō is a free Android retro launcher for organizing game libraries and configuring players to open files from selected library paths. It does not include emulators; users install their preferred emulators or other apps separately. The library provides search, detailed game views, genres, widgets, and RetroAchievements, with metadata scraping and controller navigation listed. Appearance options include downloadable wallpaper packs, theme colors, and widgets. Platform configurations can be imported from Pegasus or shared platform JSON files, or created from manually added players. The project lists connections to RetroAchievements, IGDB, RetroArch, Libretro, GitHub, and Arcade Italia DB. Its maker says the app has no backend, keeps basic user information on the device, and does not send or share that information with the maker, while third-party services may have separate privacy policies. A universal-distribution APK is provided on the latest release page. Daijishō is currently closed-source and accepts issue reports and suggestions through its repository.

RetroHub is a free frontend for organizing, displaying, and launching a retro-game library on Windows, macOS, and Linux. A first-time setup wizard helps configure it, and users can import games and settings from supported frontends. The app supports more than 80 systems and more than 50 emulators, while allowing users to add settings for others; it does not include emulators. Game metadata and media can be customized, and the built-in ScreenScraper feature can identify games by file hash or filename and fetch related information and images. ScreenScraper applies hourly and daily API quotas, and scraped media for a large library may take more than 1 GB of disk space. Users can change themes, and theme development can shape the interface and add features. Inputs include keyboard, mouse, controller, and touch; keyboard and controller actions can be remapped. The interface adapts to screen size and aspect ratio and includes a screen-reader option. RetroAchievements is an optional integration. Source code is MIT-licensed, while official builds use GPLv3 due to bundled third-party libraries.
