The C64 uses the same CIA for keyboard scan and joystick sensing.  The joystick
sends characters from the upper left of the keys and the fire button is a blank.
Games which use joystick and/or keyboard stay away from those keys.  The
second joystick, I believe, uses the output strobe bits and thus does not 'send'
characters.

You can only get so much hardware into the c64 box.
