I went and downloaded the latest version of DOSBox (7.1 something) and was going to load the lastest version of Defend, u kno the frontend, and found that it has been taken down by the author.
So I tried DOG frontend and it is working very nicely. I'm still experimenting with the frame skipping and other tweeks mentioned here. (thanks all). But I'm having a blast playing MOM again!
I was looking for some free icons to import to the DOG icon folder, but was too impatient to look for long, afterall I do have a world to conquer.
