This is a way to create Overlays for the Vectrex.

Attention: Patriots is a GREAT Game by John Donzilla. The example overlay I'm using in this Video is NOT designed by me. I really love this game and pretty much every vectrex game as well :-D

#1 Print two foils, one is mirrored.
#2 Paint the back on the mirrored one
#3 Allign the two sheets
#4 Allign a blank foil, any strenght, on the back(!) for support
#5 Weld it with a soldering iron
#6 Cut the edges and the notch

Well done, you have your own diy overlay.
