Dox recently dumped a PCB version of Treasure Island (running on the Burger Time HW),it boots fine but there are encryption issues so it isn’t working…
Then I’ve looked at a Pro Tennis romset,which runs too on the Burger Time HW (rom-swap of Disco No. 1).It’s a pity it’s not an original PCB but a bootleg that is really likely to be a lot similar to the original one:
While I was looking at these,another Data East romset got my attention: a fortune teller machine with a LED array as a display named Destiny Horoscope.
(Notes: video emulation is probably full (!) and I don’t know if it will be added to MAME,we’ll see…)
