| 1 | PS2 | ||
| 2 | ====== | ||
| 3 | SDL2 port for the Sony Playstation 2 contributed by: | ||
| 4 | - Francisco Javier Trujillo Mata | ||
| 5 | |||
| 6 | |||
| 7 | Credit to | ||
| 8 | - The guys that ported SDL to PSP & Vita because I'm taking them as reference. | ||
| 9 | - David G. F. for helping me with several issues and tests. | ||
| 10 | |||
| 11 | ## Building | ||
| 12 | To build SDL2 library for the PS2, make sure you have the latest PS2Dev status and run: | ||
| 13 | ```bash | ||
| 14 | cmake -S. -Bbuild -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=$PS2DEV/ps2sdk/ps2dev.cmake | ||
| 15 | cmake --build build | ||
| 16 | cmake --install build | ||
| 17 | ``` | ||
| 18 | |||
| 19 | ## Hints | ||
| 20 | The PS2 port has a special Hint for having a dynamic VSYNC. The Hint is `SDL_HINT_PS2_DYNAMIC_VSYNC`. | ||
| 21 | 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. | ||
| 22 | |||
| 23 | ## Notes | ||
| 24 | If you trying to debug a SDL app through [ps2client](https://github.com/ps2dev/ps2client) you need to avoid the IOP reset, otherwise you will lose the conection with your computer. | ||
| 25 | So to avoid the reset of the IOP CPU, you need to call to the macro `SDL_PS2_SKIP_IOP_RESET();`. | ||
| 26 | It could be something similar as: | ||
| 27 | ```c | ||
| 28 | ..... | ||
| 29 | |||
| 30 | SDL_PS2_SKIP_IOP_RESET(); | ||
| 31 | |||
| 32 | int main(int argc, char *argv[]) | ||
| 33 | { | ||
| 34 | ..... | ||
| 35 | ``` | ||
| 36 | For a release binary is recommendable to reset the IOP always. | ||
| 37 | |||
| 38 | Remember to do a clean compilation everytime you enable or disable the `SDL_PS2_SKIP_IOP_RESET` otherwise the change won't be reflected. | ||
| 39 | |||
