Well, picked up a complete BT kit and a "new" (to me) cassette deck and installed them on my Deco BT cocktail. After reseating some boards and reflowing solder to the cassette control connection on the Bios board I no longer have any cassetter error messages. However, the game hangs up on the blue screen with no countdown timer. After comparing the two cassette decks I noticed that the belt on the original one had disintegrated. The belt on the newer deck looks good. Not sure what to do at this point, so if anyone has any suggestions, let me know. I have a series 3 boardset by the way.
