For the STGs, there were pretty much CAVE's entire repertoire, at least one version of each game. The only ones I'm not sure if I saw were Donpachi and Deathsmiles II.
There were also a few of Raizing's STGs. Armed Police Batrider and Battle Bakraid shared a cabinet. And there was Battle Garegga of course. Great Mahou Daisakusen was also present, as well as Soukyugurentai.
HEY also has more Toaplan STGs, beyond just Tatsujin Oh. There's, well, Tatsujin. And unfortunately, these two were the only ones I remember, but I think there were more.
Psikyo was also represented, with the Strikers and Gunbird games. Couple of Capcom STGs too.
