RetroBat vs Rocksmith+

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.

Rocksmith+ is Ubisoft's music-learning service for guitar, bass, and piano. Its expanding library includes official recordings and covers across rock, hip hop, pop, metal, soundtracks, Latin, and classical. The service tracks and analyzes playing and provides instant recommendations. Practice tools include Riff Repeater, Adaptive Difficulty, interactive video lessons, and sheet music. The Free to Play plan costs nothing and includes lessons and a selection of 20 songs; a subscription unlocks the full licensed song catalog. Paid access starts at $7.99/mo, with listed options for one month, three months, and a 12-Month All-Access Plan. The service runs on Android, iOS, and Windows and includes progress tracking and cloud saves, but not offline access. On PC, playing requires a persistent internet connection, a guitar or bass, and separately purchased connection equipment. Supported instrument connections include ASIO and WASAPI devices; Ubisoft recommends compatible hardware supporting 16-bit, 48 kHz operation.
