This is a mod for the PC version of Frogger 2: Swampy's Revenge that replaces all the CD audio tracks with the Dreamcast version's audio tracks which have been converted to work on the PC version. The Dreamcast version contains updated audio tracks which are not on the PC and PS1 versions because those use older versions of the game's soundtrack.
The full game is included with this due to most people not having access to dumping via the redump method. All you have to do is mount the bin/cue files with either Daemon Tools or Alcohol 120% and run the game with the disc inserted. You can also apply this to the EU version if you have a dump that matches this one and replace/rename Tracks #2-12 with the ones included in this mod: redump.org/disc/35413/
