Subject: Strange interrupt timing
|
Ahojka!
Once again I have some trouble with Plus/4 specs:
All of the emulators I can reach I tried to run Castle Master. All was failed after the intro, because of a misplaced CLI, which enables interrupt too earlym just a long before the $FFFE-$FFFF adresses were set. (If you wanna try to find, somewhere around $8100 in the unpacked program, 8-10 NOPs follow it.)
As I remember it worked on Plus/4, sometimes crashed because of this error, but usually worked properly.
So I would like to ask then: what does a real Plus/4 do after CLI and before command? Are the disabled interrupt requests dropped?
I tried to fix in this way (CLI drops all the actual interrupt requests),
but it does not work, and other programs got mad.
Any idea again?
