Here's the second batch of photos, from 1993 and 1994:
AM Show 1993
The guy in the middle is supposedly Jaleco's Jun Saito. Not that I could recognize him...
I think this is some kind of fortune teller machine
Space World 1993
Only one tiny image for this one, unfortunately.
Tokyo Toy Show 1994
This is the oldest photo where I've ever seen the classic bathing suits on a video game event.
Super Famicom Earth World 1994
Earth World used to be the counterpart of Nintendo's Space World, not open for the public but only intended for the press and industry.
Lord British was there, too, probably to promote some Ultima SNES port.
