Забивается буфер клавиатуры как быть?

Question

[Типа Программист]

Есть простая игра где обрабатываются нажатия только если они есть

mov ah,01h
int 16h
jz p0
mov ah,0
int 16h
p0:

Вот так, далее едет код который делает задержку ибо иначе игра летит на бешаной скорости

mov ah,0
int 1Ah
mov [wait_commets],dx 
pcomm1:
mov ah,00h
int 1Ah    
cmp dx,[wait_commets]
jz pcomm1

И тут вся беда из за задержки буффер клавиатуры успевает забиться, начинает пищать спикер, если не полностю забился то все нажатия обрабатывает с задержкой.

игра где обрабатываются нажатия только если они есть...
из за задержки буффер клавиатуры успевает забиться

Что мешает вставить код опроса и чтения клавиатуры внутрь цикла задержки?

Я в цикл задержки затолкал очистку буффера, чтоб оставлялась только последняя нажатая буква, но при этом почему, когда зажимаю клавишу, оно ее как-бы с задержкой замечает что-ли
- Нажато
- Не нажато
- Нажато.

Хотя я при этом ее просто держу зажатой.

Впринципе если так будет понятней вот код

Разбираться в чужом кривом коде сложно поэтому.
Есть другие варианты решить, или я не так делал?

Спасибо, сделал как вы сказали поместил обработку нажатий в цикл ожидания, работает отлично, думаю мне это еще не один раз пригодиться)
