First thing I did was lay out the image 4up in photoshop. Then I flipped it horizontally so it was wrong reading. When you're using inkjet trasparency, you'll notice that one side is rough and made to accept the ink. The first time I printed it the black wasn't very dense at all, so I adjusted levels in photoshop and get a pretty nice black. Here is a pic of the printed sheet.

Next thing I did was get some 3M Super 77 and gave a sheet of white 20# bond paper a light dusting. Then I cut out one of the overlays and layed it down on the paper.

I couldn't find my trusty exacto, so I just cut this one with scissors. I don't have an intellivision, so i couldn't tell you how well this thing will work in the actuall controller. It's about 1 20# bond sheet of paper thicker than the original overlays.
