Battle.net vs RetroBat

Battle.net is a free game launcher and companion app for Windows, macOS, Android, and iOS. The desktop app gathers games in one library, launches them, and installs games and patches; while running, it can keep them updated automatically. Players can browse the store for games and expansions, send digital gifts, and find free-to-play titles including Overwatch 2 and Call of Duty: Warzone. Games and some in-game purchases may cost extra. Social features include messaging, voice chat, friend connections, and real-time updates. News includes sales, trailers, and patch notes. The mobile app supports shopping, social features, news, and account safety, including chat, friend presence, and friend requests. Users can enable two-factor authentication. Offline mode works only in selected games: downloads and updates need an internet connection, and social features and matchmaking are unavailable offline. World of Warcraft versions and game modes are installed through the desktop app.

RetroBat is a free, open-source Windows frontend for organizing and playing retro game ROM collections. It supports more than 230 consoles and computers and can run from a PC, hard drive, or USB key. The setup does not include emulator programs; an internet connection is required to download additional emulators. Library metadata can be scraped from ScreenScraper, TheGamesDB, HFSDB, ArcadeDB, and IGDB. ScreenScraper is the default and requires credentials. Retrieved information may include ratings, images, videos, maps, manuals, and pad-to-key settings. RetroBat also lists downloadable themes, shaders, bezels, netplay, cheats, save states, and rewind. Major Windows-compatible controllers should work, with X-Input recommended for best compatibility. Supported operating systems are Windows 11, Windows 10, and Windows 8.1. The plan is free, and help is available through Discord, the forum, and the FAQ.
