They are Mechwarrior 2 loyalists, you might pick up some hints there. I couldn't get Dosbox to work in Windows7. Best i could do is get the video clips to run but the games wouldn't load. I have an old, original box running Windows 98 with original equipment and an old CRT monitor (23") so I can run everything from Mechwarrior2, Mercs, Ghost Bear, Pirates Moon, and Mechwarrior3. Others folks seem to get their old games running, but I think that MW was pretty advanced for its day and Dosbox has a problem with it. Wish you the best, if nothing else you can find an old box that works, or build one from Ebay parts. Don't forget that you need a pretty good video card or the gameplay may be choppy. Wish you the best, they are terrific games!
