The fixes the problem of PLAY_BIG not being implemented on some modern drives. The problem now is that some old drives use BSD encoding in the MSF case, which they dont tell, and which is also not according to spec *sigh*. Hopefully there are not too many of those still alive, or I hereby grant license to kill the firmware writers that wrote the mess.
