I have seen many titles that keep running in the background when the home button is pressed. The actual callback created by sceKernelRegisterExitCallback is only called when the exit is selected from the home button but I assume that there is another callback to the main thread that tells it to pause itself.

I was looking through the list of kernel exports and sceKernelCreateCallback looks like a possibility but I don't know the necessary parameters or what the callback function should look like.

Has anybody else looked into this yet?

sceKernelCreateCallback() creates the callback, not sceKernelRegisterExitCallback().

Although maddogjt1 may have been incorrect with the process for creating the callback, he is correct that the callback for exit never triggers its function (ie exit_callback) unless they really do exit, which I assume is used in retail games for some sort of cleaning up. I would also like to know if anyone has figured out how to trap the fact that the button was pushed at all - which I think was his main question. Whenever the screen saver comes on or the home button is pressed I seem to get phantom keypresses in my app(which may be my fault - still trying to debug it) but being able to tell home was pressed would at least allow me to pause the game so that the timers stop, etc..


This all may have been addressed in skippy911's controller.c (http://forums.ps2dev.org/viewtopic.php?t=1708&) but controller_home.rar doesn't seem to be hosted at the link he posted anymore.

- Update:

I solved my problem of catching the home key, when home is pressed the key value returned is '65536'. Hope that is what you were looking for maddogjt1..
