Cool! The background pics for those 3 are on my page, when you want them.
I also took pics of the LCDs and backgrounds from the other games I have: Gradius, Lone Ranger, Blades of Steel and Star Trek 25th Anniversary, but I haven't vectorized those yet.
I'm going to deglob all but ST so I can visually dump the ROMs. I'm going to use a logic analyzer on ST since it has a 2nd glob, presumably for speech. That might help if the chip isn't well known.
