Assuming you have a legal base copy of Jump Force (v1.00) or an existing cracked version, here is the standard procedure for applying the v3.01codex update:

Step 1: Verify your base game. The CODEX update requires Jump Force-CODEX (the base cracked release from 2019). It will not work on the Steam version without manually stripping Denuvo first.

Step 2: Download the update files. Look for the archive named Jump.Foce.Update.v3.01-CODEX. It is typically 8-10 GB compressed. The archive contains:

Step 3: Apply the patch. Run Setup.exe. Point it to your JUMP_FORCE root folder. The tool will check file integrity before injecting the new assets (character models, stage data, balance files). Do not interrupt this process—it takes 15–30 minutes on HDD.

Step 4: Copy the crack. Navigate to the CODEX folder. Copy JUMP_FORCE.exe and the Engine folder into your root directory. Overwrite all files.

Step 5: Verify the version. Launch the game. On the main menu, check the bottom right. The number 3.00 should appear. If you see v.01codex in the crack text, it is successful.

In the chaotic world of anime fighting games, Jump Force stood as a ambitious, albeit flawed, monument to Shonen Jump’s 50th anniversary. Long after its servers went quiet and official support ended, a specific string of text continues to circulate within modding communities and pirate forums: Jump Force Update v3 01codex.

For the uninitiated, this keyword represents two things: the final official balance patch (Version 3.00) and the specific cracked release group (CODEX) that unlocked the game’s DLC and bug fixes for offline users. But what exactly is in this update? Why is it still relevant years after the game’s delisting? This article provides a comprehensive, 2,000+ word deep dive into every character tweak, system change, installation method, and legal loophole surrounding the Jump Force v3 01codex phenomenon.


Warning from modders: Do not update the CODEX crack to the official 3.01 (Steam). There is no actual official "v3.01"; if you see that, it’s a typo. The only valid versions are 1.00, 2.00, and 3.00.


Because CODEX unlocked the executable, modders have created "super patches" that build on v3.00. The most famous is Jump Force: Overhaul (Version 2.0).

The CODEX crack unlocked all 4 Season Pass 2 characters that the official update introduced:

Note: The crack also retroactively unlocked Season Pass 1 characters (Majin Buu, Law, All Might, etc.) without needing to buy the pass.

Jump Force presents a unique legal case. As of February 7, 2022, you cannot legally buy the game or its DLC on Steam, PlayStation Store, or Xbox Marketplace. Licenses for the anime characters expired.

Therefore, the Jump Force Update v3 01codex exists in a gray area:

Conclusion: If you own a discarded PS4 disc of Jump Force, many archivists argue that downloading the v3.01codex for PC constitutes a "format shift" because you legally own a license to the base game.


Officially, Bandai Namco pushed out Title Update 3.00 in February 2020. It was a massive overhaul that added four new DLC characters (Shoto Todoroki, Hiei, Meruem, and Yoruichi) via the "Characters Pass 2," alongside a new stage (The Umbras) and a slew of PvP balance changes.
