Still remains some issue in FBA with BGM music. It causes later in the game a z80 music data error and z80 queue full error messages but i guess XingXing, iq_132 and Haze will fix it soon.
Hope also Knights of Valour: Aoshi Sanguo (ver. 202CN) (kovshxas), a nice kovshp bootleg will be also added to MAME soon...
