TODO:
|
||||
-Add coin counter,coin lock etc.;
|
||||
-Controls dynamically changes if you turn on the Panel Type DIP-SW,I'd imagine that the "royal
|
||||
panel" is just a dedicated panel for this game;
|
||||
-Player-2 inputs are unemulated;
|
||||
-"Custom RAM" emulation: might be a (weak) protection device or related to the "Back-up RAM NG"
|
||||
msg that pops up at every start-up.
|
||||
-Video emulation requires a major conversion to the HD46505SP C.R.T. chip (MC6845 clone)
|
||||
-Video emulation requires a major conversion to the HD46505SP C.R.T. chip (MC6845 clone),
|
||||
there's an heavy x offsetting with the flip screen right now due of that (sets register
|
||||
0x0d to 0x80 when the screen is upside-down)
|
||||
-You can actually configure the coin chutes / coin lockout active high/low (!), obviously
|
||||
MAME isn't really suitable for it at the current time;
