How to make a delay, and so that the keyboard remembers pressing?

Question

assembler

I’m doing a mini game
, something is already working, somehow ...
But here such a problem in the emulator lags, but when the program starts, it flies so I don’t have time to understand what and how,
I found such a delay
mov ah, 86h
mov cx,0FFFFh
mov dx,0FFFFh
int 15h
Accumulated and pasted it and put the delay into the loop, it turned out to be what you need :)
But now after the delay it doesn’t react that I pressed something only the first time ...

mov ah,01h
int 16h       
mov si,0000h

Here is such a great two big pieces to skip (Where copy-paste) is not enough to succeed. And it no longer reacts to pressing the key, and the ball in the game is more accurate than the @ symbol Lelit itself further calmly, and the board sticks to the edge in the direction in which the
PS key was pressed for the first time: The task is difficult because I'm stupid, the code is great, and my Russian, calligraphy, etc. is lame

Answer 1

CX - timeout in microseconds (highest part)
DX - timeout in microseconds (lower part)

Thus you give the command to wait
0xFFFFFFFF = 4294967295 µsec ≈ 4295 sec = 1 hour 11 minutes 35 seconds.
