First, let's decode the name. Yakyuken is the Japanese rock-paper-scissors game (specifically the "fist" variant). The title is a pun—Yakyu also means baseball.
The game presents a simple loop:
It’s a digital adaptation of the "strip rock-paper-scissors" games found in Japanese arcades in the late 80s and 90s. The "All Star" refers to a roster of five real gravure idols of the era: Mai Haruna, Reiko Nakamori, and others. The gameplay is shallow, the FMV (full motion video) is grainy by modern standards, and the "reward" is... modest at best.
On paper, it is not a good game. Yet, it persists in collector circles.
Unlike other PSP models, the Go uses a 272 MHz CPU base (overclockable via CFW to 333 MHz). All Star Yakyuken Battle runs smoothly at default clock, but some mini-games (like the “Speed Janken” contest) benefit from a slight overclock.
Recommended settings via VSH Menu (press Select in XMB):
Also, enable "NoDRM Engine" under Advanced Configuration if you experience black screens—this helps with Japanese anti-piracy checks embedded in some 2007-era titles.
Here’s where PSP Go Custom hardware shines. The Go’s slide-out gamepad places the D-pad and face buttons closer together than the original 1000/2000/3000 models. In All Star Yakyuken Battle, this reduces thumb travel time during rapid janken selections.
Custom button mapping (via CFW’s macro plugin):
Install MacroFire plugin on your PSP Go Custom to create turbo macros for the “Special Training” mode, where you need 50 consecutive janken wins. Without a turbo function, the late-game AI is nearly impossible.
Include clear README and installer instructions with screenshots, plus an easy rollback method (how to restore original EBOOT) and a short FAQ addressing legality, CFW risks, and compatibility.

The All Star Yakyuken Battle series (also known as All Star Janken Battle) is a niche Japanese franchise for the PlayStation Portable (PSP) that blends classic rock-paper-scissors (Janken) gameplay with adult-oriented entertainment. Running this title on a custom PSP Go offers a unique way to experience the series, though it requires specific modifications due to the hardware's limitations. Game Overview
The series consists of multiple entries, notably All Star Yakyuken Portable and its sequel All Star Yakyuken Portable 2.
Gameplay Mechanics: The core loop revolves around winning rounds of rock-paper-scissors against various opponents. Success typically rewards the player with FMV (Full Motion Video) sequences.
Regional Specifics: These are Japanese NTSC-J releases. While the PSP is region-free for games, the menus and audio are entirely in Japanese. Performance on a Custom PSP Go
A "custom" PSP Go typically refers to a unit running Custom Firmware (CFW) and potentially featuring hardware mods like increased storage.
Storage & Format: Since the PSP Go lacks a UMD (disc) drive, you must run these games as digital ISO/CSO files via CFW. Because these titles rely heavily on high-quality video files, they can take up significant space—often 1GB or more per "UMD Video" disc.
Screen Quality: The PSP Go is widely considered to have the best screen of the PSP family. Its smaller, denser display makes the FMV content in All Star Yakyuken look sharper and more vibrant compared to the larger PSP-1000 or 3000 screens.
Bluetooth Features: A unique advantage of the PSP Go is its Bluetooth support, allowing you to sync a DualShock 3 controller for a more comfortable experience during extended play sessions. Hardware Considerations
If you are looking for a custom PSP Go to play these titles, consider these common community modifications:
M2 to MicroSD Adapter: Standard PSP Go memory cards (M2) are expensive and rare. A custom mod using a ribbon-cable adapter allows for 128GB+ MicroSD cards, which is essential if you plan to store the entire All Star Yakyuken library.
Battery Upgrades: Heavy FMV playback drains the PSP Go’s relatively small battery quickly. A custom unit with an upgraded battery is highly recommended for portable use.
Ergonomics: The Go's sliding design can be cramped for some users. Many users utilize 3D-printed grips to improve comfort during gameplay.

To get All Star Yakyuken Battle (also known as All Star Janken Battle) running on your PSP Go, you must first install Custom Firmware (CFW) to bypass the device's lack of a physical UMD drive. 1. Install Custom Firmware (CFW)
Since the PSP Go is a digital-only device, CFW is required to play backups of UMD games.
Check Version: Ensure your PSP Go is on the latest official firmware, typically 6.60 or 6.61.
Recommended CFW: Use ARK-4 or Infinity 2.0 with PRO-C for a permanent installation that persists after rebooting. Installation: Connect your PSP Go to your PC via USB.
Download your chosen CFW files and copy the UPDATE folder to /PSP/GAME/ on your internal storage.
Launch the installer from the Game menu on your PSP and follow the prompts to install. 2. Prepare the Game File
File Format: Ensure your game file is in .ISO or .CSO format.
Directory: If it doesn't already exist, create a folder named ISO in the root directory of your PSP Go's internal storage (the very first folder you see when opening the drive on your PC).
Transfer: Copy the All Star Yakyuken Battle.iso file directly into this ISO folder. 3. Launching and Customizing
The All Star Yakyuken Battle (also known as All Star Janken Battle) is a series of Japanese titles for the PlayStation Portable (PSP) centered on the traditional game of Yakyuken—a variation of Rock-Paper-Scissors where the loser typically removes a piece of clothing. While originally released as official UMD (Universal Media Disc) titles, the "Custom" aspect refers to the modern preservation and modification of these games on the PSP Go, which lacks a physical disc drive.

Released primarily in Japan, the series includes titles like All Star Yakyuken Portable and its sequel.
Gameplay Mechanics: Players engage in high-stakes Rock-Paper-Scissors matches against various "idols" or digital opponents.
Media Format: These were often released as UMD Movies or interactive videos rather than standard interactive games, featuring high-quality (for the time) FMV (Full Motion Video) sequences of Japanese idols. The "Custom" PSP Go Experience
The PSP Go (model N1000) is a unique, slide-screen version of the PSP that relies entirely on digital storage. Because All Star Yakyuken Battle was a physical UMD release, playing it on a PSP Go requires a "Custom" setup involving Custom Firmware (CFW).

became a cult legend.

(野球拳), or "baseball fist." Originating in Shikoku as a local performance art involving shamisen music and dancing, the game involves players performing rhythmic movements before a final "Janken" (rock-paper-scissors) showdown. By the 1950s, the game took on a popular "stripping" variation in variety shows and adult entertainment, where losers would remove an item of clothing for every lost round.

The "story" of the game is one of endurance and skill. Players travel to scenic hot spring locales to challenge these idols. Each match consists of five intense rounds; winning all five in a row unlocks special sequences and secret passcodes. The PSP Go Custom Legacy

Here’s what you need to know:
The PSP Go is the only PSP that supports Bluetooth and DualShock 3 controllers natively.
All Star Yakyuken Battle is essentially an interactive video. The PSP Go has a unique feature: Video Out. However, the game is region-locked and resolution-specific. Here is how to "Custom" enhance it.
The PSP Go (2009) was Sony’s radical, forward-thinking failure. It had no UMD drive. It was digital-only, relying on the now-defunct PlayStation Store.
Here’s the issue: All Star Yakyuken Battle was never released digitally. Ever. Not on PSN, not on PSP Go’s native storefront. The only official way to play it was via the original Japanese UMD.
For a PSP Go owner in 2010, the game was simply impossible to play. Unless…
