Hello!!
I recently purchased a multirom cartridge for my Vectrex and now I'm about to make the overlays.
I have seen that there are reproductions of several colleagues in the forum and sales through ebay... but I wanted something that was really cheap.
After looking for the necessary materials and my almost zero knowledge of printing and image modification, here is my first overlay.
Doing calculations... I can say that each overlay costs €1
Materials: Color/laser printer (I think we all have some kind of printer), laminating machine, transparent printable sheets, sheets for the laminator, cutex, scissors and ruler.
You must have a home laminating machine (the cheapest on Amazon €20).
Remember: I have looked for the cheapest way possible to make an overlay that does its job. It is normal, that with other higher quality materials... the result will be better. But I assure you that with the cost of €1 you can already play.
Printer consumption (ink): €0.15/overlay
Transparent sheet: €0.70/sheet
Laminating sheet: €0.15/sheet
