Credit to

- The guys that ported SDL to PSP & Vita because I'm taking them as reference.
|

|
|
- David G. F. for helping me with several issues and tests.

|
## Building
|
||
|
|
To build SDL2 library for the PS2, make sure you have the latest PS2Dev status and run:
|
||
|
|
```bash
|
||
|
|
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](https://github.com/ps2dev/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:
|
||
|
|
```c
|
||
|
|
.....
|
||
|
|
|
||
|
|
SDL_PS2_SKIP_IOP_RESET();
|
||
|
|
|
||
|
|
int main(int argc, char *argv[])
|
||
|
|
{
|
||
|
|
.....
|
||
|
|
```
|
||
|
|
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.
