+- Discrete sound part? There's a Rossini's "William Tell" bgm on the Chinese bootlegs,
+ I think it's tied with ay8910 port B.
- add backup ram emulation;
- unknown memories;
+- Garbage on the window tilemap if you win, it could be a BTANB (masked by the color prom).
- the name "King Derby" is a raw guess, there's a chance that it uses a different name
(but there isn't any title screen on the game?)
