syltefar.com: Raiden II
6357 The Musée Mécanique had a Raiden II machine, but it was super difficult to jump into and I didn't get very far.
9300 Unlike its predecessor, this game has immediate continues (you never lose progress), which makes it trivially beatable. It also has a dipswitch for Easy mode, which is of course not at all easy, but only slightly less unfair than Normal. This is a great looking game, I should play it.
