In the hopes that some things have been fixed in the last year (GAME_CONTROLLER init time, etc) Make sure this does not regress #2691

Nintendo 3DS
SDL port for the Nintendo 3DS Homebrew toolchain contributed by:
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:
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. SDL_GetBasePath
returns the romfs root instead of the executable's directory.- The Nintendo 3DS uses a cooperative threading model on a single core, meaning a thread will never yield unless done manually through the
SDL_Delay
functions, or blocking waits (SDL_LockMutex
,SDL_SemWait
,SDL_CondWait
,SDL_WaitThread
). To avoid starving other threads,SDL_SemTryWait
andSDL_SemWaitTimeout
will yield if they fail to acquire the semaphore, see https://github.com/libsdl-org/SDL/pull/6776 for more information.
