I figured out why the first To Heart game, version 1.0, had no sound. It wasn't because the audio files were corrupted, but because of a bug that prevented the game from finding the audio files in the CUE file However in version 3.0 To Heart Renewal Package, the developers fixed this issue and the game now has sound. But, they've slightly altered the audio track pacing compared to version 1.0 They've moved the audio track to the beginning of the next song before switching to the next audio file The solution is 1 Disable Windows autorun or autoplay 2 Install version 3.0.Then, open the version 3.0 game using Daemon Tools Lite with the version 1.0 CUE bin file. This should restore sound to the first To Heart game and the pacing should be correct
