Plans
In their own words
Daijishō
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.
RomM
RomM is a free, self-hosted app for scanning, enriching, browsing, and playing a ROM collection. The project says it supports more than 400 platforms, including multi-disk games, DLCs, mods, hacks, and manuals. Compatible games can run in a browser through EmulatorJS and Ruffle without setup, while saves and states sync across devices with conflict resolution. Metadata providers include IGDB, ScreenScraper, LaunchBox, and MobyGames; RomM can also fetch artwork from SteamGridDB and track RetroAchievements. A built-in patcher applies ROM hacks and translations. The project lists granular per-user permissions, OIDC single sign-on, a REST API, and exports for ES-DE and Pegasus. Official clients include a Windows Playnite plugin, the Android Argosy handheld launcher, and the Linux Grout handheld client. A native iOS app is a community project, and the team says it does not regularly review community project source code. RomM is AGPL-3.0 licensed, with no tracking or paid features. Setup help and community discussion are available through Discord.
