SDL Home key input

I've just been getting into using SDL on the PSP. It works very well, all besides the Home key. I can't get any button press on the Home key to register.

Here's my code:

Code: Select all

...
SDL_Joystick *joy=0;

if&#40;SDL_NumJoysticks&#40;&#41;>0&#41;

joy=SDL_JoystickOpen&#40;0&#41;;
...
if &#40;SDL_JoystickGetButton&#40;joy, 2&#41; &#41; &#123; sceKernelExitGame&#40;&#41;; &#125;
if &#40;SDL_JoystickGetButton&#40;joy, 12&#41; &#41; &#123; sceKernelExitGame&#40;&#41;; &#125;

If I press the Cross button, the game will exit, but if I press the home button, nothing happens. I don't need this for my game or anything, but I was wondering if anybody else had ran into this problem?

I'd imagine it'd only register if your application is in kernel mode. Is it?

For 3.xx user-mode apps, there is a prx floating around that will get the home button for you. It's part of SNES9xTYL, for example.

Nope. Why would it only register then?

Because the home button is normally caught by the PSP OS to display the home screen. It isn't handled by games.
