To understand the game, one must first understand the concept of Yakyuken (野球拳). The word translates directly to "Baseball Fist." It originated in the early 20th century as a street performance, often associated with festival entertainers.
The premise is simple but highly physical: two people face off. They chant a traditional baseball cheer ("Yakyuken!"), mimic the motions of a baseball player (pitching, swinging a bat, or catching), and strike a pose on the final beat. The loser of the round—determined by a Rock-Paper-Scissors (Jan-Ken) mechanic hidden within the poses—must remove an article of clothing.
By the 1980s and 90s, Yakyuken had evolved from a physical comedy routine into a staple of Japanese adult entertainment, particularly in VHS videos and early arcade games, where the goal was to strip a female opponent down to her underwear (or beyond, depending on the censorship laws of the era).

Yakyuken Special is a PlayStation port of an arcade game developed by SUNSOFT (known for Hebereke and Waku Waku 7). The concept is absurdly simple yet brilliant: For two decades, this game was a footnote
However, unlike a normal game of janken, this one features special characters, power-up meters, and a bizarre "Ecchi" (risqué) element that became the game’s unintentional marketing hook. When a batter hits a home run, a short animation plays featuring a pixelated anime girl performing a fan service pose. This "reward" system cemented the game’s reputation in the underground scene as a "sexy baseball game."
The PSX is one of the most emulated systems in history (via DuckStation, ePSXe, and RetroArch). Because the original Yakyuken Special was never released in North America or Europe, emulation via an ISO rip is the only way for Western fans to play it legally (if they own the original disc) or practically.
