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 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.
