I would make some more, but it looks like the cheapest I can get the super Joys, the main component, would be $28. Add shipping, the rest of the parts, labor, and it would end up about $90 total. Anybody still want one?
It's still cheaper than buying a NES and all those games when you think about it. But it's still a lot.
@Zipper, sorry for not seeing your post there. I dont know if you will get this or not, but I'm glad to answer your questions.
1: Yes. And yes. Some super joys use other components than a 7805, but they still do the same thing, that is output +5V.
2: Nope, not really. Other than the 7805, I took out the controller board completely and just used the original NES controllers board and IC in place of it.
3: It's a crystal. I believe it's used for the timing on the refresh rate for the TV lines. Or something like that! I don't know much about electronics. Mine was... Well I don't know, because i don't have a single picture of the right side of it, unfortunatly. I think your idea of switching the crystal out for the correct one for your region might work, but I don't know.
