Played some more 1984 arcade games. Generally shooters, all fine simple endless ones but nothing that really wows for 1984. Think things like Gaplus and Gyrodine (which admittedly has some nice tiny eyecandy). Hat Trick and Goalie Ghost are something you'll want to play with friends.

Great Swordsman was something different. A swordfighting game with 3 disciplines, though they all play the same except for amount of hits to win and the animations/range. You don't have many options, just a low/mid/high attack that also changes your stance. It's a one-hit affair, so it becomes about judging distance of strikes or forcing the opponent out of the arena whilst not getting struck. There are some unique ways of winning battles to, like hitting their weapon just right or very quickly striking their head.
