Shining Force CD iso

Hi, I just burned the Shining Force CD iso and music, and I can start playing in the first scenaro fine, but in the introduction to the second one when somebody comes in the room, then leaves, nothing happens. As that guy leaves the room his sprite starts to dissolve, but doesn't disappear completely, and the game freezes, but the music goes on.

Has anybody had this problem? Does your iso work fine?
tupou, are running on the real SegaCD or emulator?

This sound like you're using emulator to play the game. If so, you need to turn on Perfect Synchro. If not, then maybe bad burn.
