Sega still has a u.s. arcade division, which I just recently rediscovered. Naturally a lot of it is UFO machines and whatnot nowadays, but they do have a relatively interesting archive of older content. Each game has screenshots, brochures, and flyers, even for odd stuff like Emergency Call Ambulance. And naturally, since Sammy owns Sega now, Sammy games (and distributed Atomiswave titles like KOF) are also represented. It’s a bit out of date, only having House of the Dead 1-3, for instance, eschewing 4 (which is a fine game, by the by). But it does include such obscurities as Magnet Fever, R 360, and Hot Rod. Worth a look.
