Fans have succeeded in running Grand Theft Auto V on Nintendo Switch hardware, producing a community-made port that is not associated with Rockstar Games or Nintendo and requires a modified console with custom firmware.
The project uses the Legacy v1.0.2699 build — the same release used for PS4, Xbox One and PC rather than the older PS3/Xbox 360 edition — and was made possible after parts of GTA V’s code were adapted and recompiled for ARM following the 2023 source code leak.
The Switch build requires 49 GB of storage. To make the game operable on consoles with 4 GB of RAM, the developer reduced memory and GPU load by editing configuration files to lower draw distance and particle counts, compressing PC resources, and removing most DLCs from the port.
Performance varies with hardware and settings. Without overclocking the frame rate typically sits between 10 to 25 FPS. On an overclocked OLED Switch, players can reach around 30 FPS in less demanding scenes, but performance falls significantly in moments with many NPCs or visual effects. Overclocking tools such as sys-clk are being used to push performance. According to the developer, several patches have already been applied to the port to improve stability and speed.
In terms of playability, the port is likened to the PS3 and Xbox 360 versions of GTA V; however, the Joy-Con controllers have proven ill-suited for precise aiming and movement. The developer known as M0jso is also working on a native GTA V build for Android. The source code for the Switch port has not been made publicly available.
