Numeric Keypad * on a smaller keyboard

[Kirschsuppe]

I have a narrow keyboard without a numeric keypad. A couple of games can be exited by pressing the * (star) on the numeric keypad. How to do that? I already mapped the * to a Joystick button, but maybe this isn't the one from the numeric pad. Thanks in advance.

Maybe 3 months later someone knows?

the * on the 8 key is different to the * on a keypad some keyboards have the keypad keys mapped to a function and another key but there normally printed on the keys them self it does
and usually its fn and p if it has that function
