-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;
