RockNRoller

A 4mb freeware guitar-practice app that plays Rocksmith-format .psarc charts — built around freeware CDLC from the CustomsForge community. Runs entirely in your browser (Chromium recommended); a demo song is preloaded, and you can grant a local folder of your own CDLC. Mac and Windows applications also available.
