A fan-made attempt to bring Grand Theft Auto 5 to the original Nintendo Switch has been cancelled after its creator publicly challenged Rockstar Games and later received an alleged cease-and-desist letter.
The project, created by modder M0jso, attracted attention in September after footage showed the game running on Nintendo’s portable console at a stable 30 frames per second. The short clip featured the player flying over Los Santos, prompting widespread disbelief about how the technically demanding game had been adapted.
A promising Switch port gains momentum
M0jso continued to promote the work throughout the month, claiming that GTA Online was also planned for the Switch version. The modder specifically mentioned the possibility of bringing the Cayo Perico heist to the unofficial port.
The confidence came as Rockstar Games announced that modifying its games to operate on unofficial platforms violated its rules. The company also warned that such activity could result in a ban or account termination.
Rather than backing away, M0jso responded defiantly on social media, writing: “Try me rockstar” and adding that they did not care about the warning.
The controversy is a reminder of the legal and technical risks involved in ambitious fan projects. Readers interested in building their own gaming setups can explore RETROCADE’s arcade machine buying guide or browse DIY arcade kits for projects with a clearer hardware path.

Why the GTA 5 Switch project ended
The situation escalated when M0jso revealed that the project’s dedicated Discord server had been terminated for copyright infringement. The modder appeared surprised, arguing that copyright enforcement was weak in Serbia and suggesting that a warning from Take-Two Interactive could simply be ignored.
M0jso also said they would not be concerned if the server closure was followed by a formal cease-and-desist notice. That position changed less than a week later, when the modder said an alleged C&D letter had arrived.
The Switch port was then cancelled, and M0jso announced plans to disband the production banner behind the project. The reversal drew criticism from observers who remembered the earlier public taunts.
“I wasn’t expecting them to hit back hard,” M0jso wrote while responding to a confused fan.
The modder said taking the matter to court would be unrealistic because they did not believe they could win. They also acknowledged that repeatedly boasting about the project online would make any future legal defence more difficult.
“I didn’t know what I was getting into,” M0jso wrote, later adding: “I did get too cocky.”

What the cancellation means for fan ports
The cancellation does not change the technical achievement shown in the footage, but it highlights the limits surrounding unofficial conversions of major commercial games. A playable demonstration can attract attention quickly, while distribution, copyright claims and platform rules create much more serious obstacles.
For Australian arcade enthusiasts considering a custom setup, practical projects remain a safer focus. RETROCADE’s arcade machines, bartop arcades and arcade parts cover established hardware options without relying on an unauthorised commercial-game port.
