Daijishō vs Emulation Ninja

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.
