/*
Sega LaserDisc Hardware
Driver by Andrew Gardner from schematics with help from Daphne Source
Todo:
-Get LDV1000 games past the strange, pseudo-attract mode!
-Implement ldv1000's unknown/undocumented command 0xf2.
-Confirm DIPs do what's expected. Also, is Joystick_down really Joystick_up?
-Correct IC names/positions for the ROMs - Astron Belt schematics have conflicting data.
-Add SEGA/Hitachi VIP9500SG laserdisc player to MAME core & fix all non ldv1000 games to use it.
-Write Sprite drawing code.
-Hook up character map color PROM.
-Confirm palette code (inferred from Daphne source) once its actually used.
-Hook up OUT writes.
-Add samples.
-Confirm banking works.
-Character decoding may combine the lower 0x0800 with the upper 0x0800.
