There are 2 Versions of the 'snes AV out' style port for use with a regular front loading NES when modding. Each one comes in 2 package versions (3D-printed Port alone OR 3D-Printed Port with circuit board). Either plug is printed in a close grey color to the system, but is NOT an exact match (you can see its a bit lighter in color, this is probably how the nes looked before years of color fading lol). IT's the closest grey I've been able to find, but again do not expect an exact color match. Brief description:
Port Ver 1 - this is an 'internal port' where it will sit flush with the shell. This is a slightly harder install as you have to cut a perfect square to fit it (You can see how sloppy i did with my razor blade trying to score the plastic out, I do not recommend using a razor blade by the way, its tedious and ugly looking!). This can be glued to the inside of your system or optionally you could use the holes and screw if you wish. Do not over-tighten screws as you can crack the plastic of the Port or your system (these older systems are getting brittle!)
Port Ver 1 + circuit board - is the same port seen above, but comes with the DB electronics circuit board you would soldier your wires too.
Port Ver 2 - This is an 'external' port as I like to call it, as it sticks out past the shell of the system and has a boarder that can cover your sloppy cut marks. You can see how much better it looks with my crappy cutting job (and you can still see a slice mark or two, cuz i just suck at cutting!!). I prefer this version as it allows for a lot of leeway especially if you cut your square hole a little too big, This can still be glued onto the system and will look nice if you position it correctly. PLEASE be informed, that with this particular plug when you plug in your Snes style AV cable, the box part of the plug will sit about 1-2mm away from the port even when fully plugged in. IT's totally an ascetical thing (looks), it has NO impact on performance. Just part of the design.
Port Ver 2 + circuit board - Same port as above, but comes with the DB electronics circuit board you would soldier your wires too.
Please keep in mind you will need an M3-0.5 x 6mm screw to keep the circuit board in place (IT IS NOT INCLUDED!), these can be found at home depot for like 99 cents for a pack of 3 in their metric drawers.
shipping will be USPS
