+## 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.
