Tenkaichi3Decomp (Budokai Tenkaichi 3 PC port)

Budokai Tenkaichi 3, developed by Spike and published by Namco Bandai, came out on PlayStation 2 and Wii in 2007 and never had a PC release. z3xox created the Tenkaichi3Decomp repository on 6 October 2026 and published v0.1.0 the same day; by 20 October there had been dozens of releases, up to v0.1.38, and the repository had more than 500 GitHub stars. We couldn’t find press coverage of it yet.

What it is

• The game’s own code compiled for PC: the source comes from BT3-Decompiled, a matching decompilation of the USA release by the same author, with the PC changes kept apart in the code.
• A new layer underneath: a Vulkan renderer that recreates the PS2’s effects (outline, glow, depth tint, distance blur), an OpenGL 3.3 fallback, sound, input and a settings window.
• Made with the help of AI, the README says, without giving details.

Because the decompiled game code is in the repository, the README says that part belongs to the game’s rights holders and is not the project’s to license. The game’s data, and the values of its built-in data tables, are read from your disc when you set it up. It sits alongside the other console projects in our recompiled games list.

Current status

What works, per the README:

• boot, opening movie, menus, saving, fights and two-player split screen, with music, voices and effects;
• internal resolution from 1x to 8x and 4:3, 16:9, 21:9 or wider without stretching the fight;
• optional smooth motion that draws extra frames for 60, 120 or 240 FPS while the fight still runs at 30;
• rebindable keyboard and controllers, PCSX2 texture packs, and extra stages and songs dropped into folders;
• a Cheats tab with the developers’ leftover “unlock everything” function;
• online play (experimental, from 0.1.8): the hidden Dragon Net Battle menu entry opens a room-code lobby with rollback, chat and no port forwarding, and Windows and Linux players can face each other. Room codes go through a small matchmaking service, which keeps your name and address for at most ten minutes, and a relay is used only when routers block a direct link.

Known problems: the README says most of the work is on the processor, so a recent mid-range CPU is recommended; both online players need the same release; the 32-bit Linux build has no rollback; and online play on macOS hasn’t been tried. On 21 October 2026 there were 57 open issues. We didn’t play the game through ourselves.

What you need

• A disc image (.iso) of your own unmodified USA PS2 copy of Budokai Tenkaichi 3 (SLUS-21678). We don’t explain how to obtain or copy game data.
• Windows 10 or 11, or Linux with glibc 2.35 or newer, on a 64-bit x86 CPU.
• A graphics card with Vulkan (OpenGL 3.3 works as a slower fallback) and about 4 GB of disk space.

How to install

From the official README, at a high level: download the Windows or Linux build from the project’s GitHub Releases page, unpack it, run the Tenkaichi3Decomp-setup program, choose your disc image and press Play. The setup checks that the image is the unmodified USA release and unpacks the game’s data next to the program. In the game, F1 (or Start + Select on a controller) opens the settings. Linux users and Mac users can also build from source with the included install script.

Other Budokai Tenkaichi 3 projects

• BT3-Recomp, also by z3xox: a separate PC port made by static recompilation with PS2Recomp, which translates the game’s machine code into C++ at build time from your disc, with an OpenGL renderer. It is a different technique from Tenkaichi3Decomp, which compiles readable decompiled source. On 21 October 2026 we found no published releases for BT3-Recomp, and its last code update was on 1 October, while Tenkaichi3Decomp ships builds every few days and has online play. It is listed separately in our recompiled games list.

Is it legal and safe?

• Tenkaichi3Decomp is an unofficial fan project, not affiliated with or endorsed by the game’s developers, publishers or rights holders. The README says it distributes none of the game’s assets. The repository does contain the decompiled game code, which the README says belongs to the rights holders.
• Use only an image of a copy you own.
• Get it only from the official GitHub repository. The README warns that websites letting you play BT3 in a browser are not affiliated with the project, and that its releases are free, with no ads, accounts or payments.
