Funai / Gakken Esh's Aurunmilla laserdisc hardware
Driver by Andrew Gardner with help from Daphne Source

Notes:
    (dumper's note) Esh's Aurunmilla can be played in an Interstellar cabinet by swapping the
                    main pcb and the laserdisc. Sound & video pcbs are the same. Control panel is different however.
                    Esh's Aurunmilla can be a 2 player game, while Interstellar is a 1 player only game.
    Hold down TEST while resetting the machine - pops up test mode where...
    The DIPs are software-controlled.
    Two joysticks appear in the IO TEST, but the photos of the control panel I've seen show only 1.
    Eshb has some junk in the IO TEST screen.  Maybe a bad dump?

Todo:
    - LD TROUBLE appears at POST. Sync/timing issue?
    - Performance spike after some time of gameplay, CPU comms gets corrupt?
    - How to init NVRAM? Current defaults definitely aren't.
    - Wrong overlay colors;
    - Convert to tilemaps (see next ToDo for feasibility).
    - Rumor has it there's an analog beep hanging off 0xf5?  Implement it and finish off 0xf5 bits.
    - NVRAM range 0xe000-0xe800 might be too large.  It doesn't seem to write past 0xe600...
    - Maybe some of the IPT_UNKNOWNs do something?
    - Hook up LED's to the MAME lamp system.
