Famicom to NES Adapter will fit inside a NES cartridge shell. However, due to it's size you will may need to remove certain post. At the very least not try to put a screw in the center screw.

I own and use a top loader, so i've never tested the CIC feature. Tested working on my Top Loader. This is a diy project and you use it at your own risk. Any damage you do to your hardware or self is your responsibility. I offer no support for this project.

For the 60 pin edge connector, I did have to push in the pins to solder it to the board. As I use them to fix Famicoms. There maybe a better option out there.

The ceramic Capacitor is a .1uf

1.2mm Thickness

Edge Connector: ENIG and 30 degree Bevel

Surface Finish: ENIG

I'll update, if and when I find a front loader nes.
