(MESS) nes: Properly implemented the Bandai Karaoke Studio expansion
slot. The two Senyou Cassettes (Top Hit 20 Vol 1 & Vol 2) have now to be 
loaded with the following commands "mess nes -cart karaoke -cart2 top20v1" 
(or top20v2). This is accurate to the hardware, because these expansions
had to be manually inserted into the body of the main Karaoke Studio cart 
before playing. [Fabio Priuli]
