KONAMI’s e-Sports series emerged in the 1990s as a reaction to Japan’s insatiable appetite for pro baseball. Unlike the MLB-centric MLB 2K or EA Sports Baseball in the West, KONAMI focused on Japanese leagues, mirroring regional pride in games. The first Yakyuken title (1994 for Super Famicom) set the standard, but the PS1 version elevated the genre with 3D sprites and immersive stadium soundtracks. Disc 2 arrived in 1998, building on this foundation with new teams, modes, and graphical tweaks—reflecting the PlayStation’s maturation as a platform.
The game was never localized. Nihon Create is no longer active in the console space, and the original publisher has folded. The game is considered "abandonware" by many preservationists, meaning no company is currently selling it or enforcing copyright. However, official ROM sites avoid hosting it due to its adult themes.
The Yakyuken Special PS1 Disc 2 ISO is more than just a file; it is a legend among emulation enthusiasts. It represents the final piece of a puzzle that most players never got to complete. Because the physical disc is becoming unreadable due to age, the ISO is the only way future generations will experience this strange artifact of Japanese gaming history.
If you manage to find a verified, working ISO of Disc 2, treat it as a digital treasure. Archive it, share it with preservation projects like Redump or the Internet Archive, and take a moment to appreciate the weird, wonderful, and slightly pervy corner of the PlayStation 1 library.
Final Verdict: The game itself is a 6/10. But the hunt for the complete Yakyuken Special experience? That is a 10/10 retro adventure.

The Yakyuken Special: Konya wa 12-kaisen (The Baseball Fist Special: 12 Rounds Tonight!) is a notorious Japan-exclusive title for the PlayStation 1. Originally developed for the 3DO and ported to the Sega Saturn, this "adult-themed" puzzle game became a cult curiosity due to its FMV-based gameplay and its unofficial, unlicensed nature on the PS1. What is Yakyuken Special?
"Yakyuken" is a traditional Japanese group game that evolved into a form of "strip rock-paper-scissors". In this video game adaptation, players compete against various female opponents in matches of Jan-ken-pon (Rock, Paper, Scissors).
Gameplay Loop: For every round you win, the opponent removes an article of clothing.
The Stakes: If the player loses five times, the game ends immediately.
Production Style: The game uses full-motion video (FMV) sequences featuring real-life models rather than animated sprites. The Significance of Disc 2
The PlayStation 1 version of the game is typically distributed as a two-disc set. Because FMV files take up massive amounts of storage compared to standard game code, the roster of opponents is split across multiple discs.
Disc 1 vs. Disc 2 Content: Disc 2 contains the second half of the 12-woman roster. Opponents like Mai Misaki, Nao Takenaka, and Miyuki Kurakawa are often found on the second disc of the PS1 version.
Why an ISO?: Since the PS1 version was an unofficial pirate/unlicensed release, it is rare to find physical copies outside of specialized Japanese retro shops. Most modern players access the game via ISO files (disc images) for use on original hardware with a modchip or through emulators.
