Hi,
I play in the PC version of DM using DOSBOX. Almost all works perfectly. There is only a slight problem with the flashing/blinking cursor.
Cursor (hand) flashing only in the area shown in the picture:

In this video you can see it clearly:

How do I fix this?

Hello 3DH
I don't think it can be fixed.
It happens because every time the main viewport is refreshed, the cursor is drawn after ; but as the display is not buffered until the full image is drawn, it then makes the cursor blinks ..

Is there some DOSBox parameter mentioning
Vertical Retrace or Vertical Synch?
Commonly these things are handled by
waiting for Vertical Synch to do video
screen updating. Perhaps DOSBox is
ignoring this because of a setting.

I do not know, maybe in the source files.

Hello all,
I've now come across this issue running the PC version of DM in DosBox. I've found that increasing the CPU cycles with F12 actually reduces the effect, almost to the point where it doesn't blink at all, and without effecting the 'speed' of the game or animation etc. However, the cycles are so high that it puts a lot of strain on the system.
In the years since this post, has anyone found a more elegant solution to this problem?
