Bumping with some 1984 arcade. Got to play some Pac-Land, but people are familiar with that and likely with the 1st Ninja-kun as well. There was also Pandora's Palace which is likely the first ot include Konami's Moai enemy, but is otherwise an unremarkable DK clone released only in America and as a kit. There are 3 game I'd like to mention.

Oozumou is a later DECO Cassette game about sumo wrestling. Ultimately it's a simple reaction and mashing game because of the system, but it's a somewhat unique settingm quite playable and looking decent. You'll have to set up a proper mashing controller if you want to beat a full tournament as the stronger enemies give you very little leeway to fully mash. It's got a unique scene if you rank up to Yokozuna (iirc).

Off The Wall by Bally-Sente is another one of their simple multiplayer sports games. It's essentially the currently popular game of padel, except your players rotate their arms around entirely and (luckily) it's in 2D. This means you only need to angle your receive. The net goes up as the rally goes on.

Finally Mysterious Stones: Dr Kick/John's Adventure. This game takes the egg kicking element of Technos' previous games and puts them in an Indiana Jones setting maze. Complete with traps and treasure rooms. The goal is to find a treasure room and exit the maze to have it evaluated. The egglike objects roll around when kicked and can damage enemies (and launch you), break them and they might contain score, power-ups and enemies (the important one being the key ghost).
