Hm ... that explains all my doubts about the pause key ...
Ohter thing .... Why you want to hide your VDP handling routines ?
I just don�t know why the good programmers don�t want to show how to
do
that incredible VDP tricks to the beginer proggramers ....
I�m sure that if they open that secrets to every one we will have more
good programmers on the MSX ....
