What happens if you don't? Does it not register the keypresses?

I assume so. Isn't a smaller delay enough, though? Personally I would hate if the delay was too long because then the game starts slowing down, which is bad if you are using grayscale.

Yeah, like if I'm holding down 2nd it'll go on sometimes.

The "Pause" command is a a loop of "djnz $+0" commands which is equivalent to about 850 nop's per pause number.

The original getkey(#) command waited 8 clock cycles which I think is enough for 6MHz.  getkey(0) was a separate routine which only waited 4 clock cycles.  I have now merged the 2 into a single command that waits 13 clock cycles which might be enough for 15MHz.  As a result, the getkey routine is a little larger, but each call to getkey(0) is 3 bytes less now, so the program size would actually go down if you were using it more than once.
