The PlayStation 1 (PS1) version of The Yakyuken Special: Konya wa 12-kaisen
is an unofficial, pirated port of an adult-themed Japanese game originally released for the 3DO and Sega Saturn. The gameplay is a simple simulation of strip yakyuken, a variant of rock-paper-scissors where the loser removes an article of clothing. Gameplay Mechanics
Objective: Beat 12 female opponents in rock-paper-scissors matches.
Core Loop: Each match begins with a live-action FMV (Full Motion Video) of the opponent dancing. After the dance, you choose rock, paper, or scissors.
Outcome: Winning a round forces the opponent to remove one of five articles of clothing. Losing costs you one of five life points.
Control: On PS1, you use corresponding face buttons to make your selection after the prompt appears. Disc 2 Content
Because the game relies heavily on high-quality FMVs for its time, it was split across two discs to accommodate the large video files.
Opponents: Disc 2 typically contains the latter half of the 12 opponents, including specific models like Ai Ichinoki, Rie Kouno, Yukari Kousaka, and others found in the extended roster.
Exclusivity: The PS1 version reportedly includes 3–4 exclusive girls not featured in the original 3DO or Saturn versions. Critical Reception
Game Quality: Reviewers generally describe the "game" part as almost non-existent. It relies heavily on RNG (Random Number Generation); your choice often doesn't matter as the game determines if you win or lose before you even press a button.
Visuals: As an FMV game, its main "draw" was the use of real actors rather than sprites. However, the content is considered dated, absurd, and "creepy" by modern standards.
Tone: It is strictly an adult game (X-rated in Japan), featuring uncensored nudity (breasts and buttocks), though genitals are typically obscured or not shown by camera angles.
Difficulty: The PS1 port is noted by some as the most "generous" version regarding win rates compared to the notoriously difficult Saturn version.
The Yakyuken Special is viewed today more as a historical curiosity—a "time capsule" of the 1990s Japanese FMV craze—rather than a title with genuine mechanical depth or entertainment value. The Yakyuu Ken Special: Konya wa 12-kai Ikusa – Review
