# Nintendo 3DS
SDL port for the Nintendo 3DS [Homebrew toolchain](https://devkitpro.org/) contributed by:
- [Pierre Wendling](https://github.com/FtZPetruska)
Credits to:
- The awesome people who ported SDL to other homebrew platforms.
- The Devkitpro team for making all the tools necessary to achieve this.
## Building
To build for the Nintendo 3DS, make sure you have devkitARM and cmake installed and run:
```bash
cmake -S. -Bbuild -DCMAKE_TOOLCHAIN_FILE="$DEVKITPRO/cmake/3DS.cmake" -DCMAKE_BUILD_TYPE=Release
cmake --build build
cmake --install build
```
## Notes
- Currently only software rendering is supported.
- SDL2main should be used to ensure ROMFS is enabled.
- By default, the extra L2 cache and higher clock speeds of the New 2/3DS lineup are enabled. If you wish to turn it off, use `osSetSpeedupEnable(false)` in your main function.
