Played some 1984 arcade games. A decently divided set too. Some Mahjong, some secondary conversion kits, some olympic-em-ups and even a few I'd recommend. Seeing a barely legally distinct Br'er Rabbit (Jack Rabbit) arcade game was surprising, but Italy is a Donald Duck comic country after all.

Hole Land is a decent Spanish fixed shooter. The eponymous holes allow the enemies to hide as they come down all the while a volcano or two are spitting rocks that will temporarily take you out. If an enemy gets to the bottom, they'll move around near you and you'll have to jump over them. The 3rd stage is different in that formations of enemies will come at you followed by a boss that requires shooting out all of its teeth to beat.

Picrel is Itazura Tenshi, a multidirectional "shooter" where you do more evading to get a bow than actually shoot. Your goal is to form links between stars to make a constellation. Some enemies will actively hurt that process (and you if you hit them). The girl in the topright looks very Lemmingesque.
