# Building

To build SDL2 library for the PS2, make sure you have the latest PS2Dev status and run:

cmake -S. -Bbuild -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=$PS2DEV/ps2sdk/ps2dev.cmake
cmake --build build
cmake --install build

# Hints

The PS2 port has a special Hint for having a dynamic VSYNC. The Hint is SDL_HINT_PS2_DYNAMIC_VSYNC. If you enabled the dynamic vsync having as well SDL_RENDERER_PRESENTVSYNC enabled, then if the app is not able to run at 60 FPS, automatically the vsync will be disabled having a better performance, instead of droping FPS to 30.

# Notes

If you trying to debug a SDL app through ps2client you need to avoid the IOP reset, otherwise you will lose the conection with your computer. So to avoid the reset of the IOP CPU, you need to call to the macro SDL_PS2_SKIP_IOP_RESET();. It could be something similar as:

.....
SDL_PS2_SKIP_IOP_RESET();
int main(int argc, char *argv[])
{
.....
main
#define main
Definition SDL_main.h:143

For a release binary is recommendable to reset the IOP always.

Remember to do a clean compilation everytime you enable or disable the SDL_PS2_SKIP_IOP_RESET otherwise the change won't be reflected.
