as i know this kind of K-box s/w is built by the programmers.. Dun think they'l share it wif u all as shareware..

I personally got a set at home which caused me around 3k+(a cpu + monitor + remote),in 2~3yrs back.. i'm planning to add in new songs my own but the database was locked wif password ~.~ couldnt access it.. Haix, this is the way they earn money
