4 Fun in 1 follows a common practice in the unofficial-board circuit: bundling several small games of uncertain origin onto a single multi-game board to display as "new" in arcades that couldn't afford licenses. There's no reliable spec sheet on exactly which titles it includes or who put it together. As a catalog piece it's interesting more for what it represents — the informal economy of small-arcade business — than for its own playable merits, which are, at best, those of the games it repackages.
