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 message pops up after each cycle in attract. NMI-related? + - Convert to tilemaps (see next ToDo for feasibility). + - Apparently some tiles blink (in at least two different ways). + - 0xfe and 0xff are pretty obviously not NMI enables. They're likely LED's. Do the NMI right (somehow). + - 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. +*/ + +#include "emu.h" +#include "cpu/z80/z80.h" +#include "machine/laserdsc.h" +#include "machine/nvram.h" + + +class esh_state : public driver_device +{ +public: + esh_state(const machine_config &mconfig, device_type type, const char *tag) + : driver_device(mconfig, type, tag) { } + + device_t *m_laserdisc;
