Japanese and Western fighting game communities are clashing head-on over a fan-made PC port of Tekken 6. Sparked by a single post from a Japanese professional gamer, the debate has escalated into a clash of values—pitting criticism of unauthorized copyright infringement against counterarguments that it is an effort to preserve a game with no official way to play.
At the center of the controversy is 'Tekken6 Native Online', an unofficial PC port released on the 12th KST by a Czech developer known as Ekspym. Instead of emulating a console through an emulator, the project uses recompilation—recompiling the Xbox 360 version's program code for PC to run natively on Windows—while adding rollback netcode, online lobbies, and ranked matches. The distribution package contains no game data; instead, users supply their own Xbox 360 disc image, which is converted and compiled directly on the user's PC. The recompilation work was built upon a project released by another developer in September. Prior to this, Ekspym unveiled a version early this month that added rollback netcode to the PS3 version running on the RPCS3 emulator.
The response was massive. According to statistics shared directly by the developer, 9,574 accounts were created between the 12th and 17th, with 6,044 unique users actually playing matches. During that period, a total of 111,052 matches were played.
As the game gained traction, Japanese professional gamer Dogura (Ryo Nozaki) ignited the copyright debate. Known for his career in titles like BlazBlue, Guilty Gear, and Street Fighter, he posted on X on the 18th, writing, "A pirated version of Tekken 6? That crosses the line way too much, and I'm creeped out that no one overseas is raising a negative voice about it." He added that if fundamental values and moral standards differ to this extent, a real conversation might be impossible, expressing hope that appropriate action will be taken. The post surpassed 11.7 million views in just two days.
Japanese industry figures also added weight to the criticism. Ichiro Mihara, Vice President of ARIKA, who served as an online battle network code advisor for Tekken 8, posted on the afternoon of the same day that he was astonished to see people using accounts with identifiable personal information to defend unauthorized copying and copyright infringement. He questioned what would happen if he arbitrarily built netcode for Fatal Fury: City of the Wolves and released it without the rightsholder's permission. Among Japanese users, concerns persist that if players and money flow into unofficial servers, official services will suffer and could lead to the discontinuation of the franchise, alongside arguments that the lack of a re-release does not grant users a right to play.
In contrast, Western users largely argued that fans were simply finding a way because Bandai Namco has provided neither a PC version nor a re-release featuring rollback netcode. They contend that because users must supply their own game files, it does not steal revenue from Bandai Namco. Arya Tayebi, host of the Tekken YouTube channel 'That Blasted Salami' and the podcast 'Wavedash', noted that the project is an Xbox 360 recompilation rather than emulation and does not distribute the game itself, pointing out that "legality and morality are separate issues." However, he acknowledged that circumventing copy protection or recompiling copyrighted code could pose legal issues in Japan.
The argument put forward by Western fans stems from the situation Tekken 6 finds itself in. Released in 2009 for the PS3 and Xbox 360, the game never received an official PC release. The mainline Tekken series only began releasing on PC with Tekken 7 in 2017. While the Xbox 360 version was added to Xbox One backward compatibility in January 2017, and the PSP version was released in 2023 as a Classic title for PS4 and PS5, it does not support multiplayer. Consequently, there is currently no official way to play online matches with rollback netcode.
Meanwhile, the developer left room to back down. On the night of the 17th, Ekspym stated, "I didn't make this online for other people; I made it for myself," adding that they would immediately take down the service if Bandai Namco contacts them saying they do not want it or if Bandai Namco makes Tekken 6 officially playable online. They explained that when they originally posted it while having only 20 followers on X just to find a few people to play with, they had no idea it would grow this big. In the same post, they also pushed back against views discrediting the project solely because AI was used, emphasizing that AI is merely a tool.
Bandai Namco has yet to issue an official statement. The project remains online, continuing to receive updates as of the early hours of the 20th KST.
There are precedents for copyright holders taking decisive legal action against similar projects. In 2020, Nintendo responded to an unofficial PC port of Super Mario 64 built from decompiled code with DMCA (Digital Millennium Copyright Act) takedown notices. In 2024, Nintendo settled a lawsuit with the developers of the Switch emulator Yuzu, agreeing to a $2.4 million payout and a complete cessation of development. Japan also penalizes services that circumvent technical protection measures under its Unfair Competition Prevention Act. In 2021, a man was arrested on suspicion of violating this law for modifying and selling save data for The Legend of Zelda: Breath of the Wild.
However, it remains to be seen what decision Bandai Namco will make regarding this port, which does not directly distribute game data itself.
