Thinking of doing a project, and if it works out well then I may do a limited batch. I was inspired by looking at the front of the SMB3 cart. What I want to do is paint the grey top of the NES the same yellow shade as the cart label (excluding the black trim), and then custom-order a decal of the SMB3 logo and the Mario graphic and then apply this over top. I will likely get the gentleman doing the decals to also do the "Nintendo Entertainment System" text so that I can paint it over and then re-apply it for a professional look. The power LED would also be replaced by a high-intensity yellow or white one.
If I were to successfully create one and get my costs down enough that I could turn a small profit by making more, I would likely do a run of 25 or so and then make another design. It would come with a matching-color Zapper and controller (competently painted of course) and any NES I sell would have a new 72-pin connector in it. After that, I'm considering doing a blue paint-job and then doing an in-game scene from SMB with decals, or possibly a Contra one?
The only question is if anyone would be interested in getting one. I would post pics of my finished product and then go from there. I think these would be great unique Xmas gifts for anyone who enjoys NES games but doesn't have a collection themselves. What do you guys think?
