add button to config menu?

[noxx]

hello,

is it possible to add some buttons in the config menu, so that
i can start a shell script, eg "start emustation.sh", "poweroff.sh" or "reboot.sh"?

i ve only one screen, and all roms are in this list. so, it would
be nice, if i can reboot from the config menu or others.

[noxx]

ok, i think its not possible

is it perhaps possible, to open a screen with a button?
eg Joy0 Button1 + Joy0 Button2 open Screen XYZ ?
